Alternating emf of E = 200 sin 200 π t is applied to a circuit containing an inductance of 1 π henry. Then find out Equation of instantaneous current through circuit.

The given equation, E = 200 sin 2 π t , now, compare it from the general equation, E = E 0 sin ω t it means, E 0 = 200 V Now in the case of inductive reactance, current will lag with voltage in the phase of π 2 , ⇒ i = i 0 sin ω t - π 2 ⇒ i = E 0 X L sin ω t - π 2 ⇒ i = 200 ω L sin ω t - π 2 ⇒ i = 200 200 π 1 π sin 200 π - π 2 ⇒ i = sin 200 π - π 2

Alternating emf of E = 200 sin 200 π t is applied to a circuit containing an inductance of 1 π henry. Then find out Reading of a.c. ammeter connected in the circuit.
