Find the output voltage of an ideal op-amp. If V1 and V2 are the two input voltages

(a) VO= V1-V2

(b) VO= A×(V1-V2)

(c) VO= A×(V1+V2)

(d) VO= V1×V2

This question was posed to me in examination.

Asked question is from Ideal Operational Amplifier topic in portion Operational Amplifier Characteristics of Linear Integrated Circuits

Right option is (b) VO= A×(V1-V2)

Dive into clarity with: The output voltage of an ideal op-amp is the product of gain and algebraic difference between the two input voltages.
