Series vs Parallel Circuits

Explanation of series and parallel circuits and the differences between each. Also references Ohm's Law and the calculation of total resistance in each type of circuit (series and parallel).

He made a mistake for the calculation for the parallel circuit.
It's actually 0.125 + 0.125 + 0.5 which eqauls 0.75.
Then you do 1 / 0.75 which gives you 1.3

I found the music to be nice. It added to the mysteriousness since none of us know what we're doing and we're all investigating the solutions.

Thank you! You taught me in six minutes what I 've had trouble understanding for weeks in my classroom. Keep up the great work!

I didnt mind the background music. I was too focused on how informational and well said it was. Good work

[jarrydee]

Thanks for this. I been an electrician for only 4 years, NEVER had to calculate this stuff, but now that I am about to take my J-man test, I HAVE to know this. You made it very easy to understand, thank you!

[shelbysupersnake]

Damn. That kitchen example really helped me understand. Thanks!

I took 2 years of college physics and still couldn't understand this topic until now. Thanks!!

The information is valuable but the background music in this video is too loud and unnecessary. The video would have been better without background music at all.

For the longest time I have had the hardest time understanding this for a speaker application, and no matter who explained it to me I just could never 100% understand (10-20 yrs) I couldn't figure out what 1 little piece of info I was missing. Looking at from a speaker point makes it hard to learn and what this video did was make me realize that parallel is the one I'm having a problem with. I have noticed under many of these video is that people leaving still still confused and I think I just figured out how to explain it, hopefully through writing.

When you showed the 1 single yellow charge going through the parallel circuit 1 resistor at a time, It throws off what is happening. What I never understood was why in parallel does the resistance go down, that made no sense to me. It's not that the resistance goes down, but that the power output from each individual resistor get added together, making the current added together, seem like there was less resistance.

The resistance does NOT go down, it's just that when you add the powers from each resistor together, you get enough power to make it seem like the resistance has gone down.

People that do know all about this, does what I said make sense, did I finally figure it out?

in your scientific calc- 1/(1/8+1/8+1/2)= 1.3^

Thanks, I appreciate your simple to understand style and graphics, I was totally jamming out to this music too good stuff keep it up brother

[hello-nbpu]

What I learned from the comments: no one likes background music.

[amandabalash]

This is excellent...in physics 2 lab now and we haven't even been taught circuits at all (still on electric fields and force) in lecture...saved my life and grade!

Thank you for a great introduction into series and parallel circuits.

[piepienate]

Using this as last minute studying for an AP test

[avipshadawadib]

I had a great 5 minutes, I understood everything and I jammed on the music
Yay!

I choose voltage over current.

Reducing the need for heavier gauge wires, reducing voltage drops and increased arc stability (for MOTs and custom arc welders; oil cooling recommended). Possibly increasing charge as well.

Store bought welders can only be connected or wired in parallel which increases current. That will make you pay the power company more, drain more energy and make very noticeable voltage drops for your neighbors. At least you'll be able to cut metal with electrodes or get DC electrodes working on AC.

Side effects of excess current may include a very erratic arc.

You should have been my high school teacher. I might have understood it more easily back then. Great explanation, very clear. Thanks!

[bryantorressj]

My final is due tomorrow and this video helped me out on a question haha thank you so much

[CheezyC]

Wasn’t focused on the music because this explanation was seriously so awesome! Thanks, dude!
