A change of 0.04 {\V} takes place between the base and the emitter when an input signal is connected to the CE transistor amplifier. As a result, 20 \mu {\A} change take place in the base current and a change of 2 {\mA} takes place in the collector current. Find the input resistance and A.C. current gain.
