Question

define transistor,draw symbols for pnp and npn transistor ​

Answer 1

Answer:

NPN vs PNP Transistor

NPN Transistor PNP Transistor

Minority charge carrier Holes Electrons

Switching time Faster Slower

Junction biasing Emitter-base junction is in forward bias and collector-base junction is in reverse bias. Emitter-base junction is in reverse bias and collector-base junction is in forward bias.

Symbol

Answer 2

The transistor is a semiconductor device which transfers a weak signal from low resistance circuit to high resistance circuit. The words trans mean transfer property and istor mean resistance property offered to the junctions. In other words, it is a switching device which regulates and amplify the electrical signal likes voltage or current.
