Question

Derive an expression for the instantaneous current in an AC circuit containing

a pure inductor/capacitor​

Answer 1

Answer:

V equals the r.m.s value of the applied voltage. I equals the r.m.s. value of the series current. VR equals the I.R voltage drop across the resistance which is in-phase with the current. VL equals the I.XL voltage drop across the inductance which leads the current by 90o.
