if we remove the remove the feedback resistance in opamp or u can say open loop gain what happens to be output voltage if we input V1 and V 2 AT + - Terminals plz reply my doubt
the open loop gain of opamp is very high so u'll get the V1-V2 amplified if it suitably low(µV range).... if it is large then u'll have +Vcc or -Vcc at output based on whether V1-V2 is +ve or -ve...
