Question

A transistor is used in an amplifier circuit in common emitter mode. If the base current changes by 100 A, it brings a change of 10 mA in collector current. If the load resistance is 2 k and input resistance is 1 k , the value of power gain is x x 104. The value of x is______.

Accepted Answer

Correct answer: 2. (2) = i_C i_B i_B=100 μA i_C=10mA power = ( 100.1 )^2 21 power = ^2 R_0R_ in Power = 100 x 100 x 2 Gain = 2 x 104
