Answer: Voltage regulator.
- A Rectifier
- B Amplifier
- C Voltage regulator
- D Oscillator
Correct answer: C. Voltage regulator
Explanation: Zener diode is designed to operate in reverse breakdown at a specific voltage. Used as voltage regulator.
Conductors have overlapping bands, semiconductors have a small energy gap that can be bridged by heat or doping, and insulators have a large gap that blocks conduction.
Concept context
