A common emitter amplifier has a voltage gain of 50, an input impedance of `200 Omega` and an output impedance of `400 Omega`. Calculate the power gain of the amplifier.

Explanation

To calculate the power gain of a common emitter amplifier, we can follow these steps:

### Step 1: Understand the given values
- Voltage Gain (Av) = 50
- Input Impedance (Rin) = 200 Ω
- Output Impedance (Rout) = 400 Ω

### Step 2: Calculate the current gain (β)
