Question

The base forms two p-n junctions with the emitter and the collector.

(a) True

(b) False

I had been asked this question in a national level competition.

This key question is from Semiconductor Electronics in section Semiconductor Electronics : Materials, Devices and Simple Circuits of Physics – Class 12

Answer 1

Right choice is (a) True

Easy explanation: Yes, this is a true statement. The base is the middle section of the transistor that forms two p-n junctions with the emitter and the collector. It is very thin and lightly doped so as to pass most of the emitter injected charge carriers to the collector.
