Question

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, Holes, Holes
• C. Electrons, electrons, electrons
• D. Holes, electrons, electrons

Answer 1

The correct option is A Holes, electrons, ions

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
