Q. |
Which of the following is true for the cut- off region in an npn transistor? |
A. | potential difference between the emitter and the base is smaller than 0.5v |
B. | potential difference between the emitter and the base is smaller than 0.4v |
C. | the collector current increases with the increase in the base current |
D. | the collector current is always zero and the base current is always non zero |
Answer» B. potential difference between the emitter and the base is smaller than 0.4v | |
Explanation: both collector and emitter current are zero in cut-off region. |
