A common emitter transistor has a current amplification factor of 100 and is used as an amplifier the audio signal voltage across the collector resistance of 5 k `omega` is 5 V the base resistance is 2 k `omega` then

Options

A. the input signal voltage is 0.01 v
B. the base curent is 10 `muA`
C. the input signal voltage is 0.02 v
D. the base current is 5 `muA`

Explanation

To solve the problem step by step, we will find the input signal voltage (Vin) and the base current (Ib) for the given common emitter transistor configuration.

### Given Data:
- Current amplification factor (β) = 100
- Collector resistance (Rc) = 5 kΩ = 5000 Ω
- Output voltage (Vout) = 5 V
- Base resistance (Rb) = 2 kΩ = 2000 Ω
