Normally, i reduced the peak voltage to 10 volts using Auto transformer. Then, i connect the line wire to inverting terminal and neutral wire to non-inverting terminal of the op-amp.Wht i expected is 1 volt amplitude 180 degree out of phase with respect to input signal. But the signal is distorted and it doesn't show sinusoidal nature at the ouput terminal.The circuit is shown below (inverting configuration)
I test the same circuit supplying 15 volt dc signal into inverting terminal and grounding to non-inverting terminal and this circuit shows the nature what is expected of it(i.e output volts is -1.5v)
And with the same circuit, i tested with signal generator and the output which i found is +14v and -14v. I am sure the problem is the way how the voltage interacts at the inverting and non-inverting termina but not sure how the result arises. Thank you.
