The collector supply voltage is 6 V and the voltage drop across a resistor of in the collector circuit is 0.6 V, in a transistor connector in common emitter mode. If the current gain is 20, the base current is
View answer and explanation
Correct option: B
0.05 mA
Option B (0.05 mA) is correct because the base current is calculated using the formula , where is the collector current and is the current gain.
