Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

A handy nomograph quickly determines the equivalent resistance of two parallel resistors. Although you could use the standard formula and a calculator, the nomograph also lets you easily find ...

With that equivalent resistance, you can then know what the resulting current is in the circuit. Then, using Ohm's Law, you can calculate the voltage across, and current through, each resistor. OK ...

In circuits connected in parallel, the components are connected on different branches. Find out more with BBC Bitesize. For students between the ages of 11 and 14.

One of the most overlooked, but important performance characteristics of a capacitor used in power circuits is its equivalent series resistance. Ian W. Clelland and Rick A. Price, ITW Paktron ...
