Solution
Transistor:
Number of depletion layers in a transistor is two.
A transistor is an electronic component that can be used to either amplify or transfer electrical signals or power in circuits, allowing it to be used in a wide range of electronic devices.
A transistor made up of two PN diodes connected back to back. It consists of three terminals: emitter, base, and collector.
A bipolar junction transistor (BJT) is a current-controlled device that uses two PN junctions to perform its function.
There are also two areas of depletion. The thickness of the depletion layer is determined by the biasing condition applied to the junction.
Hence, the number of depletion layer in a transistor is two.
