Complex Circuits of Resistors

Physics homework example showing how to calculate the current through each resistor in a combination of series and parallel circuits. This tutorial is an excerpt from the "Topic 17-B - Resistance and Electrical Circuits" lesson in a complete course in Physics Homework Examples (including 27 topics and 230 tutorials in all topics of Physics) available on http://www.PhysicsVodcasts.com.

.05 is just the inverse of the resistance for that portion. To actually get the resistance, you need to take the inverse of that answer, which (without rounding anything in between) is 19.7

very good video but can you speak a little faster? Thanks for the great videos, keep them coming :-)

@sandiegoboy85 For some reason, she didn't invert the whole thing. Should be ((45^-1)+(35^-1))^-1. Comes out with the right number.

ahh!!! i solved this problem in just 2 min, this video is totally silly

[sandiegoboy85]

Wait how did u get 19.7, when i plugged in (45)^-1+(35)^-1 i got 0.05

It's amazing how something this simple my physics professor can't seem to get in my head, but you can. Thanks a bunch!

Thanks a lot
