Question

In N -- type semi - conductor current is due to

• A. Electrons
• B. Holes
• C. Electrons and holes
• D. none of these

Answer 1

The correct option is A Electrons

In N-type semi-conductor majority carriers are electrons. So, when the voltage is applied across the semi-conductor electrons started to drift from negative to positive terminal as result current starts to flow in opposite direction of electrons.

Hence in N- type semi-conductor current is due to electrons.
