Ω is 4V. If the base resistance is 1kΩ and the emitter resistance is 500Ω, calculate the following:
1. The voltage gain of the amplifier
We can use the formula for voltage gain in a CE amplifier:
Av = - Rc / (re + Rb)
where Av is the voltage gain, Rc is the collector resistance, re is the emitter resistance, and Rb is the base resistance.
Plugging in the values given:
Av = - 2kΩ / (500Ω + 1kΩ) = -2
So the voltage gain of the amplifier is -2.
2. The input impedance of the amplifier
The input impedance of the amplifier is simply the base resistance, which is 1kΩ.
3. The output impedance of the amplifier
The output impedance of the amplifier is the collector resistance, which is 2kΩ.
