Learn how to calculate resistance in series and parallel circuits.

How to calculate resistance of resistors in parallel Resistors R₁ and R₂ in parallel When resistors are connected in parallel , the total resistance can be calculated using the formula: ...

Series-parallel circuit. The Figure at right shows three impedances; two are connected in parallel and then connected in series with a third impedance. Each impedance can be a pure resistance, a pure ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
