One of the most overlooked, but important performance characteristics of a capacitor used in power circuits is its equivalent series resistance (ESR). ESR determines the capacitor's I2R heating ...

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 ...

The open-circuit voltage vOC is simply vT because no voltage drops across RT when i = 0. To find the Thevenin equivalent resistance RT, remove all power sources and calculate the total resistance ...

Winding dc resistance depends on the wire material, wire gauge, length of wire and temperature. Copper has a resistance of 10.371 (ohms/circular mil)' feet at 20°C.
