In a transistor, collector current is controlled by:
Correct answer: C. Base current
- A. Collector voltage
- B. Collector resistance
- C. Base current
- D. All of the above
Explanation
The correct option is base current. The collector current in a transistor is primarily controlled by the base current. By adjusting the base current, the transistor's amplification and switching characteristics can be regulated.

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.
