Physics · Alternating Current
In an LC circuit, the inductance L = 40 mH and capacitance C = 100 μF. If a voltage V(t) = 10 sin(314t) is applied to the circuit, the current in the circuit is given as:
- 10.52 sin(314t)
- 25.2 cos(314t)
- 310 cos(314t)
- 40.52 cos(314t)✓
Correct answer
0.52 cos(314t)
