A transistor is connected in common-emitter (CE) configuration. The collector supply is 8 ~V and the voltage drop across a resistor is 500 in the collector circuit is 0.6 ~V . If the current gain factor is 0.96 , find the base current

Step-by-step solution

Given, V_ C C =8 ~V Voltage drop, V₀= I_C R_L=0.6 ~V Load Resistor, R_L=500 Gain factor, =0.96 = 1- = 0.96 1-0.96 =24 Now, V₀= I_C R_L0.6= I_C 500 I_C= 0.6 500 =1.2 10⁻³ ~A Now, = I_C I_B Base current I_B= I_C = 1.2 10⁻³ 24 =5 10⁻⁵=50 10⁻⁶ I_B=50 A
