A transistor is connected in common emitter circuit configuration,...

A transistor is connected in common emitter circuit configuration, the collector supply voltage is 10V10V and the voltage drop across a resistor of 1000Ω1000Ω in the collector circuit is 0.6V.0 . 6V . If the current gain factor (β)( \beta ) is 24,24, then the base current is ____μA\mu A. (Round off to the Nearest Integer)

Correct answer

0

Step-by-step solution

β=ICIB=24;RC=1000\beta = \dfrac{{I}_{C}}{{I}_{B}} = 24; {R}_{C} = 1000

\DeltaV=0.6\DeltaV = 0 . 6

IC=0.61000{I}_{C} = \dfrac{0 . 6}{1000}

IC=6×10−4{I}_{C} = 6 \times {10}^{- 4}
IB=ICβ=6×10−424=25\muA{I}_{B} = \dfrac{{I}_{C}}{\beta} = \dfrac{6 \times {10}^{- 4}}{24} = 25\muA
