what happens to be Vo if we remove feedback in opamp

[sayurabh]

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

I think you will see Vcc at Vo.

 

[A.Anand Srinivasan]

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...

 

[Fawad Elahi]

you will get a differential output at the output.but most proberly you will get a clipped output.because the gain is very very high for open loop

 

[the_edge]

Vout=Vcc if V+>V-

Vout=(0 or Vee) if V+<V-

If V+=V- than Vout=0
