A transistor is connected in CE configuration. The collector supply is 10 ~V and the voltage drop across a resistor of 1000 in the collector circuit is 0.5 ~V . If the current gain factor is 0.96 , then the base current is

Step-by-step solution

The collector current I_C is determined by the voltage drop across the collector resistor R_C = 1000 . Given the voltage drop V_R = 0.5 ~V , we have I_C = V_R R_C = 0.5 1000 = 0.5 10⁻³ ~A = 500 A . The current gain factor in common base configuration is given as = 0.96 . The relationship between collector current I_C and base current I_B in common emitter configuration is I_C = I_B , where = 1 - . Calculating : = 0.96 1 - 0.96 = 0.96 0.04 = 24 . Now, calculating the base current I_B : I_B = I_C = 500 A 24 = 20.833
