At 0K, a semi-conductor acts like _.
Correct answer: C. Insulator
- A. P-type
- B. Minority carriers
- C. Insulator
- D. None of these
Explanation
At absolute zero temperature (0 Kelvin or -273.15 degrees Celsius), a semiconductor tends to act more like an insulator. At this extremely low temperature, the electrons are tightly bound to their atoms, minimizing their ability to move and conduct electricity, resembling the behavior of an insulator with very low conductivity.

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.
