In a comparator when V− <V+ then
Correct answer: B. Vo = - Vcc
- A. Vo=+Vcc
- B. Vo = - Vcc
- C. V = V-
- D. Vo = V+
Explanation
In a comparator, when the inverting input (V− ) is less than the non-inverting input (V+ ), the output (Vo ) is typically at the negative supply voltage (−Vcc ).Incorrect Options and Explanations: (a) Vo=+Vcc - This option is incorrect; the output is typically at the negative supply voltage in this condition. (c) V = V- This option does not correctly describe the output state of the comparator. (d) Vo = V+ - This option does not correctly describe the output state of the comparator.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
