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

Correct answer

0

Step-by-step solution

β = I C I B = 24 ;     R C = 1000 Δ V = 0 . 6 I C = 0 . 6 1000 I C = 6 × 10 - 4 I B = I C β = 6 × 10 - 4 24 = 25   μ A
