A change of 0.2 mA in the base current causes a change of 5 mA in the collector current for a common emitter amplifier. (1) Find the a.c. current gain of the transistor. (2) If the input resistance is 2 k ohm

Assuming that the resistance of the meters are negligible what will be the readings of the ammeters A1 and A2 in the circuit shown in figure ?
