Capacitors and capacitance

Capacitance (symbol C) is a measure of a capacitor’s ability to store charge. A large capacitance means that more charge can be stored. Capacitance is measured in farads, (symbol F). However 1F is very large, so prefixes

The Maximum power transfer theorem

Earlier it was demonstrated the existence of internal resistance in the power supply such as in a battery, and the effect that this resistance has on the voltage supplied to the load was discussed. The load voltage
