Question

Which of these is the odd one in the choices?

(a) Transition capacitance

(b) Diffusion capacitance

(c) Space charge capacitance

(d) Depletion layer capacitance

I had been asked this question by my college director while I was bunking the class.

My question is taken from Transition Capacitance in section Diode Circuit of Analog Circuits

Answer 1

Correct answer is (b) Diffusion capacitance

The best I can explain: Transition capacitance is the junction capacitance in a reverse biased diode. The rate of change of immobile charges wrt a change in reverse bias voltage is called transition capacitance, or space charge or depletion layer capacitance.
