  1. Question 1

    Q1. The voltage across an inductor is given by V = 100 sin(100πt). If the inductance is 1 H, the current is

    • A) 0.318 sin(100πt - π/2)
    • B) 0.318 cos(100πt)
    • C) 0.318 sin(100πt + π/2)
    • D) 0.318 cos(100πt + π)

    Answer: 0.318 sin(100πt - π/2)

    Explanation: I = (1/L) ∫V dt = (1/1) ∫100 sin(100πt) dt. After integration, I = 0.318 sin(100πt - π/2)
