A 1mv of i/p gives an output of 1V, the voltage gain as such would be

The voltage gain can be calculated using the formula:

[

text{Voltage Gain (Av)} = frac{text{Output Voltage (Vout)}}{text{Input Voltage (Vin)}}

]

In this case:

– Input Voltage (Vin) = 1 mV = 0.001 V

– Output Voltage (Vout) = 1 V

Now, substituting the values into the formula:

[

Av = frac{1 V}{0.001 V} = 1000

]

Therefore, the voltage gain is 1000.
