Question

In a pnp transistor, the current carriers are
(A) Acceptor ions
(B) donner ions
(C) holes
(D) electrons​

Answer 1

Answer:

In a pnp transistor, current carriers are holes.

Answer 2

Answer:

The right answer is option(C): holes.

Explanation:

• P-N-P transistor is a positive-negative and positive configuration, with its arrow pointing inwards in the emitter terminal.
• This uses a very small base current, making the emitter more positive than the base and the collector.
• In P-N-P, the emitter consists of a p-region or positive semiconductor region.
• The majority of carriers are holes for P-type semiconductors.
• And so, as the emitter region of the P-N-P transistor is also p-type, the majority of carriers are also holes in this case.
• Just lie the majority carriers in the N-P-N transistor are Electrons.

Therefore the current carriers are holes (positive charges) in the case of the P-N-P transistor.
