Definitions:

Electrical Response

The reaction or output of an electrical system or component when a voltage or current is applied.

Forward Bias

Forward bias is the condition in which a p-n junction semiconductor, such as a diode, allows current to flow freely from the p-side (anode) to the n-side (cathode) by applying a voltage.

Current Flow

Describes the directional movement of electric charge carriers, like electrons, in a circuit, crucial for powering and operating electronic devices.

Power Transistor

A semiconductor device used to amplify or switch electronic signals and electrical power.
