Prof Anderson is excellent. On why more people etc ... You will discover that 99.9% of people have no interest in physics or math. It's just the way it is
I have been interested in circuits from a very young age, probably introduced to my first electrical circuit around age 3. They became one of my favorite pastimes ,I think that I always knew that someday they would become part of my professional life.
I don’t know a single thing about physics, this is the first video of this channel I’m seeing, and yet some how, even though this is super far into the modules, this professors explanations are so good that I can still make full sense of what he’s talking about. What an amazingly gifted person
Just ran into this channel by autoplaying while I fall asleep at night and ended up waking up in the middle of a lecture. I very much enjoy the way you teach. I am not sure if many others feel the same way or not but in my opinion you convey the information/material incredibly well! I am out of school and no specific need to watch these videos but still find myself picking one when bored. Hope you read this or at least are told so you know you are doing a good job.
Hello sir. I'm Rakesh from India . I really appreciate your work Sir. I really liked your lectures .Thank you so much Sir . Ur lectures were there when I had hard times clearing my entrance exam for med . I would like you to know that I solved few questions in exam (All thanks to you sir) and I'm in med school now . THANK YOU SIR . ILL REMEMBER U TILL I DIE.
Prof. Anderson thank you very very much. You make me don't lose focus on your intention to teach and to transfer all contents that you wish to give. I watching your open course one by one. I am going to continue on. thank you again.
I am starting an electrical project on my boat. Having limited knowledge of electricity and having purchased a multimeter to measure various electrical factors I searched for UA-cams on the subject. I am so glad I found this series. I know it is 7 years old but mostly, if not all, still relevant. More that what I thought I would need to know but WOW electricity is no longer a (complete) mystery. Great way to present. Very good teaching.
Hi Dr Matt I am a physics teacher in Namibia. I am so delighted to have come across your lectures. My learners are equally grateful. You really make physics learning so easy and meaningful. Thank you so much for your lectures.
Atlanta, GA (Georgia State University). My E&M final is tomorrow and I'm freaking out, but your lecture videos are very helpful! Thank you for posting.
Hello Professor, I love your examples and applications: real-life situations , it makes me more appreciative how exciting Physics really is. I just wish that it is a mandatory subject to all high school students here in the USA.
SuperKwame, Excellent, way to stay energized! This was definitely one of my goals, to reach out beyond the walls of college to everyone out there that wants to learn physics. Keep it up! Cheers, Dr. A
Nah, he is just flipped the video, his students also sees the high quality video in real time in class while he is writing on the glass normally on the other side.

When teaching, it is difficult with the solution to the students, but the teachers are very persistent and the teachers understand the teacher very well when they are really good in the exercises. Asked him it would be better for me to just watch this tutorial
At about 30:55 the reference to a "Station that pumps the water back up to the top of the waterfall" as analogous to charging a battery rather aptly describes the "pumped storage" operation at Castaic Power Plant, where the turbines can be reversed to pump water back to the upper reservoir at the top at night (when electricity is but pennies on the dollar) to produce power the next day and sell it at full price. They only have to pay the state for the water the first time they use it, and the price of excess power on the grid at night used to reposition the same bought-and-payed-for water is MUCH cheaper than paying the state for brand new water.
Funny that I watched this in December 2022 and thought it was just uploaded because of the world cup messi joke (or "joke"). Then I realised it was uploaded 8 years ago. That's the thing about circuits I guess... always current. Couldn't resist. Arghh, I'll get my coat... time to go ohm.
The danger is not the clothes dryer as much as it is the house wiring. Each circuit is wired with wire of a certain thickness. Each thickness can safely allow a maximum current to flow without heating up and possibly igniting. The thicker the wire the greater the current it can safely conduct. To save money, most household circuits are 15A to 20A. That is enough for lights and small appliances. Large devices like your clothes dryer actually operate at double the voltage and have 30A circuit breakers in each line. If you are not familiar with household wiring, it works like this. The power company delivers electricity through two thick wires. Each wire has a potential of 110V to 120V relative to the ground. The electricity comes in passes through the circuit breakers to your devices then returns via a neutral wire which is connected to ground. A connection from either wire to ground delivers 110V to 120V, but if you make a connection between the two wires, each at 110V to 120V you will get double the voltage, 220V to 240V. Since power is voltage times current, doubling the voltage halves the current. Each of those two lines has its own circuit breaker, typically 30 amps each. If you look in your circuit breaker panel, you will see one or more sets of breakers that are two switches locked together, so flipping one of them flips both of them. One will be connected to your clothes dryer and the other to your air conditioner. Wires are color coded. Black (death) or red (danger) are the hot wires where the electricity is coming into the circuit, and white (benign) for the neutral wire carrying it back to ground. There is also a special safety wire which is green (ground) which is there as a back up in case something goes wrong. It is typically connected to the outsides of metal appliances to keep you from being electrocuted. One word of warning, you should never touch any bare wire whether it is black, white, or green, because it is possible to be electrocuted by any of them if something is broken in the circuit.
Protons and electrons can not only be moved by copper-wire but also by glassfibre-wire with pieces glass in it. This goes somehow quicker, the circuit of the protons and electrons wil be in a spiral-move. And it is cheaper in fabricate. I like your lessons, dr. Anderson a C to A most be possible at your lesson-subject. Thanks and kind regards. Remarks are like(d).
Very helpful video series. Thank you. Why did you plug in the "weight" of the car (2,000kg) rather than its "mass". By definitiln, the "weight" of 2000kg (typical car) already had the gravity acceleration figured into it. Unless your car actually weighed closer to 20,000kg due to the earth's gravity, then the mass would be around 2,000kg as you suggested. Am I missing something?
Patrick L, kilograms is a measure of mass, not weight. Thanks for the comment, and keep up with the physics! You might also like my new website: www.universityphysics.education Cheers, Dr. A
Question: 45:40 "There is this general drift on the charge in the direction of the current." I was under the impression that electrons move in the opposite direction of the current. Could someone please explain this?

Hello Professor Matt Anderson, my name is Fernando, I am a Retired Portuguese Engineer, aged 79, and I want to thank you very, very, very much for the way you use in your MARVELLOUS LESSONS, because you, REALLY TEACH, and we, REALLY LEARN, through REALLY SIMPLE WAY. I am interested to advise friends of mine to "assist" to those same lessons, BUT they do not understand English, and with SOME (not all ...) of the lessons, it has not been possible (at least, I could not configure my computer - in the case, a Mac) - to have Translation to Portuguese; could you be kind enough, Professor, to please inform me how to achieve to have that translation in ALL your Lessons? My Regards and Thank you, again, Fernando
The thing I'm wondering about the direction of the current is that if it's true that electrons flow to the positive side then doesn't that affect where you would put a resistor? Wouldn't you want to put it between the negative terminal and what you were trying to reduce the current to? Like if you had an LED light in the circuit wouldn't you want the resistor inbetween the negative terminal and the LED light instead of inbetween the positive terminal and LED Light, since the flow is coming out of the negative terminal and you want to slow it before it reaches the LED light? Or, does it not actually matter which side you put the resistor on?
I love your stuff, but you used the term 'Reluctance' when describing the effects of resistance. I think that may have been a bad choice of terms in this case, as 'Reluctance' is a quantity that is used, I believe, in magnetic terms. It might have been better to use the term 'opposition' to current flow in the case of resistance. (I apologize if this has been discussed before. My life is getting shorter by the second, and I don't always read previous comments.) With that said, I did get what you were trying to explain, and by watching your earlier videos, I'm not only trying to refresh what I have learned a long time ago, but also to learn it from a newer perspective. You do great stuff. don't stop.

A circuit requires at least one element? If you just connect a wire to the negative and positive that's not a circuit? That would be considered a short circuit?
Hi. in 48:17 th minute of video resistivity of gold was given as 1,72*10^-8 and at the 52:53th minutes of video same value given as copper resistivity . I think it is accidental
Electricians wish that the statement you made at about 2:10 was true. It would make their lives a lot easier and make about 90% of the NEC code unnecessary. You say the potential (voltage) at any place along a wire is the same. However, that is only true for an ideal wire that has no resistance. Such a metal wire does not exist and is very close only in superconductors. I think a disclaimer is needed. You can say that in the lab you are measuring the same potential at every point along a wire. That is because your meter cannot measure the very small change. However, when you deal with longer wire and/or higher voltage, you will be able to measure that difference. But for now we are going to ignore the very small difference. That will pave the way to differentiate those that will ignore that difference and before teachers and those that will become electrical engineers. (Not putting down teachers, I was one).

However, when you deal with longer wire and/or higher voltage, you will be able to measure that difference. But for now we are going to ignore the very small difference.
That will pave the way to differentiate those that will ignore that difference and before teachers and those that will become electrical engineers. (Not putting down teachers, I was one).
Great point, thanks for commenting.

I just wonder if this guy will ever be able to write forwards ever again.
Matt Smith,
Not writing backwards (I'm not that talented). The board is called Learning Glass. You can check it out at www.learning.glass

5:45 - he continues to forget to include, "One amp is one coulomb per second _past a given point or plane._"
John,
Thank you! Sometimes I get a little too glib.
Cheers,

17:54 Oh, I'm watching buddy. I was wondering how the hell you got 3,000 and just assumed I was wrong lol.
Awesome, thanks for watching and commenting.

I thought zen monks meditate using Ohms.
Excellent!

What kind of textbooks are using your students sir?
Matt, you know better than that, it is NOT degrees Kelvin, it is Kelvins. The temperature you wrote is 125 Kelvins.
Wayne,
You are keeping me honest, I love it! Keep 'em coming.
Cheers,
Dr. A
Can anyone test this out and give feedback? hunt for androidcircuitsolver on google
