Can some one please tell me :
Why do we connect a resistor to the negetive input of the op-amp and its other end earthed ? What is the roll of this resistor in the circuit, other than in mathematical calculation for gain ?
< Would be greatful to recieve a response at the earliest >
Thanks in advance
