A common base transistor amplifer circuit has `200 Omega` and `100 k Omega` input and ouput resistance resepectively if the current gain is 0.85 and `I_(c )=1.5` mA then

Options

A. the voltage gain and power gain are 475 and 451 respectively
B. the base current is 0.1 mA
C. the voltage gain and power gain are 480 and 475 respectively
D. the emitter current is 160 times the base current

Explanation

To solve the problem, we need to calculate the voltage gain (AV) and power gain (AP) of the common base transistor amplifier circuit using the given parameters.

### Given Data:
- Input Resistance (RI) = 200 Ω
- Output Resistance (RO) = 100 kΩ = 100,000 Ω
- Current Gain (α) = 0.85
- Collector Current (IC) = 1.5 mA = 0.0015 A
