The voltage gain of the following amplifier is

A

`10`

B

`9.9`

C

`1000`

D

`100`

Text Solution

Verified by Experts

The correct Answer is:
D

Voltage gain of the given operational amplifier is defined as ratio of output voltage to input voltage.
`A_(V)=(V_(0))/(V_(i))`
From Ohm's law `V=iR`, where `i` is current. `R` is resistance.
`:. A_(V)=(R_(f))/(R_(i))=(100 k Omega)/(1k Omega)=100`
