I should have found this video awhile ago. I was about to employ brute force memorization on these questions and now I understand them. Your presentation is great! thanks!
THANK YOU MICHAEL! Why can't every source just say that " In a series circuit the current remains constant, while the voltage varies" and "In a parallel circuit the current varies, while the voltage remains the same"? I wish they'd stop trying to dazzle us with extraneous terms and information.
I would like to see more of the math involved at each step. I still don't know how much current (amperes) is flowing because I don't know the R of the lamps. Is there a way to find that out with out using a meter? Inquiring senior minds want to know.
Hi, Alvin. This video is for teaching general principles -- leaving out the math was done very much on purpose. The point of this video is that the values don't matter when it comes to Kirchoff's Law. You are welcome to plug in any values you want for the lamps, but to demonstrate the points of the video, make them equal, then make one double the other. You could go for 10 ohms each, then 10 ohms for one and 20 ohms for the other, or 1,000,000 each, then 1,000,000 and 2,000,000. If you run your Ohm's Law calculations on them, the amounts of current will change, but the proportions will stay the same. For details on the math, check out this video: th-cam.com/video/RyWaRK1U1mc/w-d-xo.html Hope that helps!
I must be the dumbest dolt on the planet. I understand what’s being said, but not how the applications differ. I just have some trouble grasping the simplest of electronics. 😢

What a superb teacher and video. Really well done. Thank you!

Sounds like you need to stop hanging out with "them!" :-) Thanks Jonathan.
