Answer: 6.37 V.
- A 3.18 V
- B 10 V
- C 6.37 V
- D 7.07 V
Correct answer: C. 6.37 V
Explanation: For a full-wave rectifier V<sub>dc</sub> = 2V<sub>m</sub>/π = 2 × 10/π ≈ 6.37 V.
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.
