When a battery is connected to a P-type ...

When a battery is connected to a `P`-type semiconductor with a metallic wire, the current in the semiconductor (predominantly), inside the metallic wire and that inside the battery respectively due to

A

Holes,electrons,ions

B

Holes, ions, electrons

C

Electrons, ions,holes

D

Ions,electron,holes

Text Solution

Verified by Experts

The correct Answer is:
A
Charge carriers inside the `P`-type semiconductor are holes (mainly). Inside the conductor charge carriers are electrons and for cell ions are the charge carriers.
