The current amplification of the common base NPN transistor is 0.96 . What is the current gain if it is used as common emitter amplifier?

An NPN transistor is used in common emitter configuration as an amplifier with 1 k Omega load resistance. Signal voltage of 10 mV is applied across the base-emitter. This produces a 3 mA change in the collector current and 15 mu A change in the base current of the amplifier. The input resistance and voltage gain are:

A transistor is used in common emitter mode as an amplifier. Then (1) the base-emitter junction is forward biased (2) the base emitter junction is reverse biased (3) the input signal is connected in series with the voltage applied to the base-emitter junction. (4) the input signal is connected in series with the voltage applied to the base collector junction.
