I am a 3rd-year computer engineering student and I still don't understand the difference between voltage and current. Now I fully understand the difference thanks to your simple and clear explanation.
i've been working as electrical engineer for 4 years, i heard people talking about "valt" and "wattage" a lot but this is the first time I understand what they really is, this video rocks!
This video is wrong they explain it to electricians like this but engineers get told the truth. Electrons don’t flow energy is passed through magnetic fields surrounding the wire.
@@tunkunrunkbasically, voltage is the thing that pushes electron to move forward, and current is just measuring how much electron is being pushed by the voltage
@@tunkunrunk It's "easy" to explain, if the explanation is actually wrong. (Actually, voltage is like altitude, but using electrostatic forces rather than gravity forces.) And, when you get to college, if you believed the explanation in this video, you'll fail your physics-exam questions (maybe just one, if you're lucky.) Voltage is not potential energy. Voltage is something called "potentials," with little relation to energy. THINK: several different capacitors can all have the same voltage, yet different stored energy. THINK: if voltage is really just energy, why do we need "Volts" at all? Why not just use joules? Where is the specific flaw here? Well, when we divide energy by charge, *it's not energy anymore.* It turns into something weird, something called "Potentials." With a water-height analogy, voltage is like the height of the water, NOT the potential energy stored in the water. We can even remove all the water, so the energy is zero, *yet the height is still there.* The taller the water tank, the higher is the voltage, even if the water is removed and the Potential Energy is zero. Voltage and potential energy are two completely different things. Or, if our analogy involves lifting boulders, then voltage is the altitude through which we lifted the boulder. Different size boulders give us different amounts of potential energy, even while the voltage (the altitude,) stays the same. (And, if someone tries to convince you that altitude is a form of energy, you'd better be suspicious.) But what is voltage, REALLY? Here's the simplest explanation: voltage is a way to describe e-fields. Voltage is something like flux, like "force lines," but where voltage is at 90deg to the flux, and voltage appears as thin membranes, not as thin fibers. Voltage appears wherever fields appear, and patterns of pure voltage can exist in empty space. Wherever we have fields and flux, we also have invisible sheets made from "Potentials." Magnetism potentials. G-potentials. The E-potentials are called "voltage." Even simpler: there is no such thing as "static electricity," even though Electrostatics certainly exists. Electrostatics is the science of capacitors and surface-charge ...and high voltage. When dealing with Electrostatics, we're dealing with high voltage at zero current. Really, we've mistaken the voltage for the "static." When you touch a VandeGraaff generator, and your hair stands up, your hair is showing the shape of the invisible e-field. And that invisible e-field is made of pure voltage, a voltage with no current.

For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand. Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness; and your feet shod with the preparation of the gospel of peace; above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked. And take the helmet of salvation, and the sword of the Spirit, which is the word of God: praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints. The bible is no old book. You have to really let Christ open your eyes; to see the world in shambles. Many people say it's a religion to lock up people in chains, and say it's a rule book.. why? Because people hate hearing the truth, it hurts their flesh, it's hurts their pride, it's exposes on what things have they done..people love this world so much, s*x, money, power, women, supercars.. things of this world. Still trying to find something that can fill that emptiness in your heart. You can't find that in this world.. only in Christ, the bible is no chains, it's a chainbreaker.

I wish I had a teacher like you in my school. Now, I understand in 3 mins what my Physics teacher is still trying to teach me for ages! Thanks a million!
This is really helpful. my teacher always says "it's the difference in electric potential energy between two points" but I didn't really know what that exactly meant, or how it related to a real circuit.
@iris ligtenbarg I hope that you’re joking because if you’re not then firstly wtf are you doing on this video and secondly you’re one of these stupid girls who spam these emojis
I just had explosive diarrhea on the toilet after eating a chinese takeaway curry and stumbled across this video at 3am sitting on the toilet in pain. I now understand the concept of voltage and current. Beautifuly made video. Thank you
what a video man!! best explanation ever. Ive always been overthinking electricity but the more I learn the more I realise how simple it actually can be if you just snap it.
Youe explanation shows both enthusiasm & interest. Somewhere in the past I was told that voltage is push... current is movement of energy? It was years ago lol I think when you see this explanation you sort of understand the difference between doing something and knowing it well and accurately. Thank You.
Is Voltage the difference between the amount of electrons between the + and - side of the battery? Like when the battery is charged there's a lot of electrons on one side of the battery. When you close the circuit the electrons flow from the full side to the empty side. That means that when the battery is used, it's voltage drops. Am I understanding it correctly?
In AC power, current continue to flow without a losing any energy whereas voltage drops during a complete cycle? Why is that, I've thought of a scenario that if you replace the tank (potential energy) at the top of the platform with a strait pipe every time the voltage energy difference drops to zero with the water still flowing (current) and then swap back to the tank when the energy difference level is rising similar to a flow of a wave chart. With the current still flowing does that mean there is energy still available through the current? Because if the is a negative energy potential then there has to be a positive energy potential to somewhere to assist the continuous current flow. Please help me understand
0:11 Incorrect. Current is the time rate of flow of charges, not of electrons. This means that a current or 3 A (amps) does not mean 3 electrons are flowing per second, but instead 3 C (coulombs) per second. This means there are 3 * 6.24 * 10^18 electrons flowing per second, which is not just 3 as this video would imply. Furthermore, the current can even be due to protons (like salt solutions), not necessarily electrons.
Thanks for a clear explanation to electrical reasoning of any kind. It is one of those ( KEPT SECRET ) skill sets which boggles many peoples minds, even if they are professionals. For me, the hardest thing to fully grasp is the ohms law, because they have screwed it up with to many words that dont work togather for good definable understanding, and my Cousin is the inventor of the computer chip, so.... Thanks for a strait forward, easy to understanding explanation, its meaningful for all of us I'm shure. Ok, peace.
i’m still so confused like if the pd ( just the difference between two points ) is a voltage how is that an energy supply like to me that’s like saying the recorded difference in speed a car has at 2 different points is it’s motor
If you do not understand, let me try to help. You could see Voltage and Current as cause and effect. It starts with a voltage. Closing that potential with some value of resistance (wires, components) leaves you with some amount of current A 1.5V battery can produce 2 amps of current if shorted with a wire, but putting your tongue in series to this wire wont electrocute you. (Tongue has more resistance so current would be limited) Touching city AC in series will result in higher currents that can be fatal, unless the current is limited by resistance.
Hello, I bought an EverStart Jump Starter and Power Supply. It has 3 USB ports but also a regular household current plug. It says it's1200A jump start and 500W AC power. If I want to run a device (electric grain grinder) using the plug, and the grinder is rated at 10.5 amps, will this device run it?
I really like this analogy. Sometimes they describe a resistor as a diameter reduction in the pipe resulting in a lower amount of water flowing (lower current). How can this analogy still uphold if you increase the height of the water tower (increasing voltage) and therefore increase the current? I can only see this work if the diameter of the pipe scaled with the same ratio as the increase in height of the water tower since current is not the speed of electrons per second but the amount of electrons passing with the same speed per second. Just trying to get the most complete analogy here ghehe
Is the potential of a charge the energy of attracting other charges or its kinetic energy? Is the electron potential negative? What is the difference between positive and negative potential?
finally after 45 years someone explained it so my small brain can understand... if only someone showed me this when i was a kid, my life would be completely different... aaah
This is still to technical but I assume we could say that Voltage is like the horsepower of a car, Current is the speed of cars and Ampere is the number of cars per second.
The last time I read something related to electricity and physics was in 2009, my interest towards EV made me purchase a tesla and watch these videos at 1.30 AM.
So is another way to define voltage, taking electrons within two points and finding the average charge, between those 2 points? Where as current is just the charge of electrons in one point?
If it's a flow of electrons, then how does a wireless induction charger work in a vacuum? If on the receiving end, the internal cable, where are these electrons coming from?
It’s called an electromagnetic field. Anywhere electrons are there is an electric field. Metals have a cloud of loose electrons it’s why they’re so good at conducting electronic charge as energy.
But how is it that some devices draw more current than other devices connected to the circuit even though the voltage source is fixed? for example when we short circuit, the amount of current keeps increasing (reaches infinity if there is no fuse) even though we have a 10v source?
@Thaer K. Voltage is just the difference of potential energy of the charges. So if voltage is 10V and there is no resistance in this case if at once there are 20 positive charges and and 10 negative charges there will be a difference in the energies of two terminals because wire would have a smaller resistance which will dissipate energy to small extent.. And if at another time of observation there are 40 positive charges reached at positive terminal there will be 20 negative charges at negative terminal the potential difference would be increased between the component(load) and current will also increase beyond the limit of load and will cause short circuit.. But voltage source has fixed Voltage.. This means that source only regulates the flow of charges it don't tells the potential difference across terminals of load.. There always remains potential energy difference in circuit due to the resistance of wire causing steady current flow..
Its been 5 years since engineering. And suddenly at 1AM my brain wants to know what's the real meaning of voltage. So had to UA-cam it again lol.
