Enter the input resistor and feedback resistor in the below op-amp calculators to calculate the voltage gain.

**Working of Inverting Op-amp Gain Calculator**

**Inverting op-amp gain calculator** calculates the gain of inverting op-amp according to the input resistor R_{in} and feedback resistor R_{f}. The gain indicates the factor by which the output voltage is amplified, i.e. it tells how many times the output voltage will be than the input voltage. The equation to calculate the gain is given below

Gain = R_{f}/R_{in}

For example if the gain is 5, then the output voltage will be 5 times greater than the input voltage.

**Working of non-Inverting Op-amp Gain Calculator**

This **non-inverting op-amp gain calculator** calculates the gain for non-inverting op-amp according to the below equation, where R_{in} is the input resistor and R_{f} is the feedback resistor.

Gain = 1 + R_{f}/R_{in}
