The current gain can be calculated using current instead of power using Joule’s first law to calculate. In many cases, the input and output ... more
Resistors in a parallel configuration are each subject to the same potential difference (voltage), however the currents through them add

Potentiometer is a three-terminal resistor with a sliding contact that forms an adjustable voltage divider. The potentiometer can be used as a voltage ... more
The drift velocity is the average velocity that a particle, such as an electron, attains due to an electric field. In general, an electron will 'rattle ... more
