  1. Question 1

    Q1. A 3-phase AC power supply to a factory is represented by the equation ΔV = V0 sin(ωt). What is the angular frequency (ω) in terms of the frequency (f) of the supply?

    • A) 2πf
    • B) 4πf
    • C) ω = πf
    • D) ω = f/2π

    Answer: 2πf

    Explanation: Angular frequency ω = 2πf, not 4πf, πf, or f/2π.
