In Fig. is (i) the emitter, and (ii) the collector, forward or reverse biased? Under what condition does the transistor with CE configuration act as an amplifier?
Text Solution
Verified by Experts
The transistor used is p-n-p transistor. Here emitter is at `-2V `and collector at `+1V`, both belong to p-type semiconductor, hence (i) emitter is reverse biased and (ii) collector is forward biased. For a transistor to act as an amplifier, it must have the operating point close to the center of its active region.
