A pure semiconductor behaves like an insulator at _ temperature.
Correct answer: C. Absolute Zero
- A. 120°C
- B. 140°C
- C. Absolute Zero
- D. 90°C
Explanation
A pure semiconductor behaves like an insulator at absolute zero temperature (0 Kelvin or -273.15 degrees Celsius). At this extremely low temperature, the semiconductor's electrons are bound tightly to their atoms, preventing them from moving and thus behaving more like an insulator with very limited 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.
