In a common base transistor the value of load resistance in output and input circuit is 500 `komega` and 300 `omega` respectively calculate the voltage gain and power gain if value of current gain is 0.90

Explanation

To solve the problem step by step, we will calculate the voltage gain (AV) and power gain (AP) of a common base transistor given the load resistance in the output circuit (R0), the input resistance (Rin), and the current gain (α).

### Step 1: Identify the given values
- Load resistance in the output circuit (R0) = 500 kΩ = 500,000 Ω
- Input resistance (Rin) = 300 Ω
- Current gain (α) = 0.90

### Step 2: Calculate the voltage gain (AV)
