Physics · Alternating Current
An alternating voltage source V(t) = V0 sin(ωt + φ0) is applied across different electrical circuits. Match the electrical load in List-I with its correct steady-state current response in List-II: List-I (Electrical Load) A. Pure resistor R B. Pure inductor L C. Pure capacitor C D. Series RL circuit List-II (Current Response)1. i(t) = V0R sin(ωt + φ0)2. i(t) = V0ωL sin(ωt + φ0 − 90°)3. i(t) = V0ωC sin(ωt + φ0 + 90°)4. i(t) = V0√(R2 + ω2L2) sin(ωt + φ0 − tan−1(ωLR))
