Reverse Bias

Reverse bias refers to a condition in a semiconductor device, like a diode, where the voltage is applied in the opposite direction of its normal operation. In this state, the device does not conduct electricity easily, effectively blocking current flow. This can be useful for protecting circuits from unwanted current, allowing only specific conditions to generate a flow. In practical terms, reverse bias ensures that components function correctly and safely, particularly in applications like power supplies and signal processing. It is fundamental in controlling electrical signals in various electronic devices.
