Q. The voltage gain of the following amplifier isPhysics Question Image

AIIMSAIIMS 2005Semiconductor Electronics: Materials Devices and Simple Circuits

Solution:

Voltage gain of the given operational amplifier is defined as ratio of output voltage to input voltage.
$A_{V}=\frac{V_{o}}{V_{i}}$
From ohm's law $V=i R$, where $i$ is current, $R$ is resistance.
$\therefore A_{V}=\frac{R_{f}}{R_{i}}=\frac{100\, k \Omega}{1\, k \Omega}=100$
