Question

An amplifier's input voltage is 12 mV, and its output voltage is 128 mV. Calculate voltage gain.

Answer 1

Answer:

Amplifier gain is equal to 10.67.

Explanation:

Voltage gain of an amplifier can be expressed as this equation:

A_v = (V_output) / (V_input)

Where A_v is the gain, V_output is the output voltage, and V_input is the input voltage.

For this we will solve:

A_v = 128 mV / 12 mV

A_v = 10.67

So the amplifier's gain is 10.67.
