I came across this question in my text book and it says:
When does Voltage lag current by 90 degrees in an AC circuit contains only a capacitor and an inductor (its ohmic resistance is negligible).
And I thought of this:
When Xl = 2Xc.
Is my answer correct? As in the solution the book mentioned two methods and mine wasn't one of them. They are:
- When the capcitive reactance is larger than the inductive reactance.
- When we take the inducor out of the circuit.
