A germanium at 0K is
Correct answer: C. Insulator
- A. Conductor
- B. Semiconductor
- C. Insulator
- D. P and N semiconductor
Explanation
When the temperature of semicondutors is increasing, their conductivity increases and when it is kept low so conductivity decreases.Thus, it behaves as an insulator at low temperatures.

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.
