Find the input voltage of an ideal op-amp. It’s one of the inputs and output voltages are 2v and 12v. (Gain=3)
(a) 8v
(b) 4v
(c) -4v
(d) -2v
I got this question in examination.
My question comes from Ideal Operational Amplifier topic in portion Operational Amplifier Characteristics of Linear Integrated Circuits
