Question

although current is blocked in reverse bias,
select one:
o a. there is a very small current due to minority carriers
o b. there is some current due to majority carriers
o c. there is an avalanche current

Explanation:

In reverse bias, majority carriers are blocked. Minority carriers (electrons in p - type and holes in n - type) can still move, creating a small reverse saturation current. Avalanche current occurs at high reverse voltages (not the general case of reverse bias). Majority carriers are not responsible for current in reverse bias.

Answer:

A. there is a very small current due to minority carriers
