Would you prefer to use a transistor as a common base or a common emitter amplifier?

In a common base configuration, the transistor has emitter current of 10 mA and collector current of 9.8 mA. The value of base current is….

For a transistor, working as common emitter amplifier , the current gain is 45. What will be the current gain when the same transistor is worked as common base amplifier ?

If a transistor is used in common -emitter mode as an amplifier,then

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.

For a transistor in common emitter configuration, the current amplification factor is 4 . If the transistor is connected in the common base connected and change in emitter current be 6 m A , then the collector current will be
