Solution 1

The voltage gain (Av) of a common emitter amplifier is given by the formula:

Av = -RC/re'

Where: RC is the collector resistance re' is the internal emitter resistance

Given that RC = 2.2kฮฉ = 2200ฮฉ and re' = 20ฮฉ, we can substitute these values into the formula:

Av = -2200/20 = -110
