Dear Members,
I have attached the image of inverting operational amplifier. I have the following doubts
For measuring current input current Iin we take voltage drop across Ri as
Vin - Va
Similarly voltage drop across Rf as Va - Vout for the current If
My question is why not we take as Va - Vin, for the first case and
Vout - Va for the second case
The current flows from left to right in this diagram. Please help revered members
