1.	A transistor is connected in a common emitter configuration. The collector supply is 8 V and the voltage drop across a resistor of `800 Omega ` in the collector circuit is 0.5 V. If the current gain factor `(alpha) ` is 0.96 , Find the base current.
Answer» Correct Answer - B ` beta = alpha / (1 - alpha) = 0.96 / (1 - 0.96) = 24` The collector current is , ` i_c = "voltage drop across collector resistor" / "resistance" = 0.5 / 800 A = 0.625 xx 10^(-3) A ` From the definition of ` beta = i_c / i_b ` the base current ` i_b = i_c / beta = (0.625 xx 10^(-3)) / 24 A ` `= 26 mu A ` .
