Question

The instantaneous values of emf and the current in a series ac circuit are-

E = Eo Sin ωt and I = Io sin (ωt+π/3) respectively, then it is ______.

Options

• Necessarily a RL circuit

• Necessarily a RC circuit

• Necessarily a LCR circuit

• Can be RC or LCR circuit

Answer 1

The instantaneous values of emf and the current in a series ac circuit are-

E = Eo Sin ωt and I = Io sin (ωt+π/3) respectively, then it is can be RC or LCR circuit.

Explanation:

E = E₀ sin ωt

I = `"I"_0 sin (omega"t" + pi/3)`
