When an AC source of emf e = E_0 sin(100t) is connected across a circuit, the phase difference between the emf e and the current i in the circuit is observed to be \pi/4 as shown in the diagram. If the circuit consists possibly only of R-C or R-L or L-C series, find the relationship between the two elements.

Correct Answer is : R = 1 kΩ , C = 10 μ F

When an AC source of emf e = E0 sin(100t) is connected across a circuit, the phase difference between the emf e and the current i in the circuit is observed to be

as shown in the diagram. If the circuit consists possibly only of R-C or R-L or L-C series, find the relationship between the two elements.

R = 1 kΩ , C = 10 μ F
R = 1 k Ω , L = 10 H
R = 1 k Ω , C = 1 μ F
R = 1 k Ω , L = 1 H
