Q. Which of the following is true for the cut- off region in an npn transistor? (Solved)
1. potential difference between the emitter and the base is smaller than 0.5v
2. potential difference between the emitter and the base is smaller than 0.4v
3. the collector current increases with the increase in the base current
4. the collector current is always zero and the base current is always non zero
- b. potential difference between the emitter and the base is smaller than 0.4v
