In A Common-base Amplifier The Load-resistance Of The Output Circuit Is  and The Resistance Of The Input Circuit Is . If Current-gain Be 0.95, Calculate The Voltage-gain And The Power Gain.

When the p-end of the p-n junction is connected to the negative terminal of the battery and the n-end to the positive terminal of the battery, then thep-n junction behaves like :   

n-type semiconductor is formed :

An n-type and a p-type silicon can be obtained by doping pure silicon with : 

An n-type semiconductor is :

The drift current in a p-n junction is :

The diffusion current in a p-n junction is 

In a p-n-p transistor with normal bias:

The base-current of a transistor is  and the collector-current is 2.05 mA. A change of  in the base-current produces a change of 0.65 mA in the collector current. Find .  

The current-gain of a transistor in a common-base arrangement is 0.98. Find the change in collector-current corresponding to a change of 5.0 mA in emitter-current. What would be the change in the base-current?

In input and output resistances in a common-base amplifier circuit are  respectively. If the current-gain  is 0.98, then find the voltage gain. If the emitter-current is 2 mA, then find the collector-current and the base-current.
