An input voltage `V_(i)` of `0.20 V` is applied to an operational amplifier connected as shown in the diagram. What is the output voltage `V_(0)`?

`0.20 V`

`1.2 V`

`0.80 V`

`8.0 V`

Text Solution

Verified by Experts

The correct Answer is:

The circuit configuration is a non-in-venting amplifier. The gain of the amlifier is given by the equation gain `=(V_(0))/(V_(1))=1+(R_(1))/(R_(2))=1+10/2=6`
thus, the output voltage `V_(0)` is
`V_(0)=6V_(i)=6(0.20)=1.2 V`
