- We know electorns flow through a conductor at drift speed, which is a very low speed (~100 mm/s). However, when you switch on light, the elctrons instantly reach it. How this is possible? Welcome to the intersting journey of electorns from the powerplant to your home.
Short answer: the voltage induced is the important thing. The electromotive force. It would move all the electrons along the conductor because of the force instantaneously. The electrons from power plant don't have to reach your home. This is especially different as we use alternating current which will make the electrons stay on specific range as they just oscillate many times per second. Nice short answer.
It would be more interesting to clarify how energy is transmitted just by the oscillation of electrons (poynting vector)
Lots of Love. Sabin. You contribute a big part to my knowledge.
Also note that there is no connection between primary and secondary when we are dealing with transformers so even if the motion of the electron is in the hundreds of km a single electron from the plant can’t reach your house:)
But there is a noticable delay between pressing the switching and the lamp turning on. Isn't this about 20% speed of light? Aka the speed of "electricity"?
You also said that the electric field travels at the speed of light.
And that electrons travel 10cm/s.
So there are 3 different "things" going around/through a wire?
The delay is noticable with some lights (forget about the fluorescent ones) for eg. LED lights and that is maybe due to the manufacturing process involving some capacitors and inductors causing the delay.
But is unnoticeable with others.
So the manufacturer knows about the delay better.
@@hardiksethi20 I meant to try to illustrate that the electricity (whatever that exactly is) also travels at a certain speed, lower than the speed of light, but faster than the electrons. So regardless of lamp used.
Thus, making it a separated "entity" alongside the other two...
I understood your point 👍
electric field is set up in circuit with light speed.

I think you are confusing the commonly referenced "speed of light in a vacuum" (3*10^8 m/s) for the actual speed of light in a given situation. You are right that often what you call "electricity" travela slower tham the iconic 3*10^8 m/s, however, it is still the speed of light, not a separate entity! It is simply that the speed of light is not always the same, for example in different electrical circuits, especially at high frequencies, the speed of light will be 40 or 60 or 80% of the speed of light in a vacuum.
Very informative and concise! Thank you!
Where do you get this voice from? Great video as always!
You have cleared my conception, Thanks a lot.
There are 2 types of educational videos, 1 is you watch and forget, 2 is you download it into your pc ASAP, if it can get deleted from UA-cam 😉 ... this is type 2
How voltage is created in power plant.
I have a doubt . what is the use of transformer and why we need to transform voltage ? Pls answer my question and love your videos
The main function of transfomer in power plant is increasing the voltage.
Why to increase voltage?
To lower the losses.
Lower the transmission voltage..higher is the losses. Losses are mostly in form of heat.
If you are not an electrical engineer.
This answer is fine and decent.
Power lost due to transmission Lines is given by
P=R*I²
And the power at the load is P=VI
You can choose to tranfer the power either at 1)Low voltage-High current or 2) High voltage - low current
But see that P being lost is directly proportional to I².
If you choose to step up voltage by N times Current is Reduced by 1/N times and thus only 1/N² of power is lost
The other way is increasing current by N times and thus Increasing power wasted by N² times
So high voltage transmission is better
Thank you now it cleared my doubt
Amazing now i get it.
Thank you soo much.
Sir, what about HVDC systems. They are long lines of DC transmission between generating station and load. 🤔.
Hello mam For HVDC we transmit power through dc only but after transmission for distribution again this dc power is converted to Ac in substation and then fed to loads
@@rohithmarise5705 right. So in the mid portion of DC transmission what will happen!
Umm. Generating station will pass the electrons instanteneously upto hvdc station. Than we have 100s of km dc transmission, here will it take time?🤔. than again dc to ac converting station. And than load, again instanteneous.
Are Alternators jet engines?
Talk slow english 😪
This is dangerously misleading, the alternating electric field is present on any hot conductor whether or not the circuit is closed.
Yeah but in hot conductor it is very weak . And this video is right bro
I hope u watched it properly
I am big fan...
Awesome
Isn't watt equal to current multiplied by voltage? & the electricity bill is based on watt's?
& that opposes whats mentioned here?
Just like sound! Sound is the result of vibration of liquid, solids or gases bodies. They oscilate back and forth .
Nice
Awesome 👌
And of course, there are multiple transformers between the generating plant and your home, so there is no actual electrical connection for the electrons to flow through anyway ☺️
Then how electron reaches ??
On AC they don't travel, they oscillate in position, on DC they travel, but on either case they don't need to travel all the way to work, they only need to push the next electron , the chain reaction pushes the electron near the bulb, that is why it's instant even when they travel slow.
Awesome 👍
Hi , I have question
❤
Mathews You are doing a great Job...We need every school in India should give the Students equivalent to IITians....We need Brains in Crores...
What is biot-savart
I dont get the last part...if it oscillates then how does it reach our homes
Ohhhh emf field = instantly 😮
If electron can travel only 1mm in one direction then how they travel through long wires
They do travel but slowly. Think of it like pushing prinkles in the stack.
On AC they don't travel, they oscillate in position, on DC they travel, but on either case they don't need to travel all the way to work, they only need to push the next electron , the chain reaction pushes the electron near the bulb, that is why it's instant even when they travel slow.
Didn't you watched the video?
Nice
Nice explanation dude!
But i want fresh electrons!
"electrons move slow".. what an incredibly misleading statement.. electrons move at nearly the speed of light
liked it.want more videos
amazing and very interesting video 👍🏻⚡️
Such an important concept.
Awesome!
