  1. Question 1

    Q1. The gain of an op-amp is given by A = V_o / (V+ - V-). What is the typical value of A?

    • A) 10
    • B) 100
    • C) 10^5
    • D) 10^8

    Answer: 10^5

    Explanation: Op-amp gain is typically very high, around 10^5, due to its high input impedance and low output impedance.
