When base current in a silicon transistor is changed by 12 `muA` the input resistance of the transistor is 650 `omega` when this transistor is uded as a CE amplifier with load resistance of 2 k `omega` calculate
(i) the current gain
(ii) transconductance
(iiii) voltage gain of the amplifer

Explanation

To solve the problem step by step, we will calculate the current gain, transconductance, and voltage gain of the common emitter amplifier.

### Given Data:
- Change in collector current, \( \Delta I_C = 2 \, \text{mA} = 2 \times 10^{-3} \, \text{A} \)
- Change in base current, \( \Delta I_B = 12 \, \mu\text{A} = 12 \times 10^{-6} \, \text{A} \)
- Input resistance, \( R_{in} = 650 \, \Omega \)
- Load resistance, \( R_{out} = 2 \, k\Omega = 2000 \, \Omega \)
