n p n transistor

Ele. N P N ට්‍රාන්සිස්ටරය

Definition:

n p n transistor (noun): A type of bipolar junction transistor consisting of three layers of semiconductor material with a middle layer of opposite polarity to the outer layers. The layers are arranged in the order of n-type, p-type, and n-type, giving the transistor its name.

The n p n transistor is commonly used in electronic circuits for amplification and switching purposes. It operates by controlling the flow of current between the two outer layers by applying a small current or voltage to the middle layer.
