Question
A series R-L-C circuit has R=100Ω, L=0.5H, C=10μF connected to a 50Hz source v=120 sin ωt. Find the instantaneous current at t=0.10s.
Correct Answer
Option B is the correct answer.
Detailed Explanation
Z = 189.5Ω. Peak current I₀ = 120/189.5 = 0.63A. At t=0.1s, value is 0.63A
Hint
Calculate peak current and consider the time dependency.
