Q. Consider a$\ p$-$n$ junction as a capacitor, formed with $p$ and $n$-materials acting as thin metal electrodes and depletion layer width acting as separation between them. Basing on this, assume that a n-p-n transistor is working as an amplifier in $CE$ configuration. If $C_{1}$ and $C_{2}$ are the base-emitter and collector-emitter junction capacitances, then
A) $C_{1}$ > $C_{2}$
B) $C_{1}$ < $C_{2}$
C) $C_{1}$ = $C_{2}$
D) $C_{1}$ = $C_{2}$ = 0
Explanation
The correct answer is Option A: $C_{1}$ > $C_{2}$.
