Question

How is the difference voltage calculated in closed loop non-inverting amplifier?​

Answer 1

Answer:

The closed-loop voltage gain of a non-inverting amplifier is determined by the ratio of the resistors R1 and R2 used in the circuit. Practically non-inverting amplifiers will have a resistor in series with the input voltage source, to keep the input current same at both input terminals.
