In an NPN transistor circuit, the collector current is 10 mA. If 90% of the electrons emitted reach the collector, the emitter current (iE) and base current (iB) are given by
- iE = – 1 mA, iB = 9 mA
- iE = 9 mA, iB = – 1 mA
- iE = 1 mA, iB = 11 mA
- iE = 11 mA, iB = 1 mA
Answer
(D) i E = 11 mA, i B = 1 mA
