Question

explain the working of npn and pnp transistor​

Answer 1

Explanation:

In an NPN transistor, a positive voltage is given to the collector terminal to produce a current flow from the collector to the emitter. In a PNP transistor, a positive voltage is given to the emitter terminal to produce current flow from the emitter to collector. ... The NPN transistor always has an arrow pointing out.

Answer 2

Answer:

NPN and PNP transistor

Explanation:

In an NPN transistor, a positive voltage is given to the collector terminal to produce a current flow from the collector to the emitter. In a PNP transistor, a positive voltage is given to the emitter terminal to produce current flow from the emitter to collector.
