forward-conducting state

electronics
Also known as: forward-on state

Quick Summary

In electronics, a forward-conducting state occurs in a p-n junction, a boundary between p-type and n-type semiconductors. Semiconductors, like silicon, conduct electricity better than insulators but not as well as conductors.

When a positive voltage is applied to the p-type side and a negative voltage to the n-type side, the junction becomes forward-biased. This allows electrons from the n-type material to cross the junction and combine with holes in the p-type material, creating an electric current. This one-way conduction is the principle behind diodes, essential components in semiconductor switches and for converting alternating current (AC) to direct current (DC) through a process called rectification.12
