Engineering How Do You Calculate Inductance in an R-L Circuit?

[Scitt]

Homework Statement

[/B]
A resistive load takes a current of 15A at 125V, 50Hz. An inductor is then connected in series in order that the same current should be drawn from a 230V, 50Hz supply. Assuming the inductor has no resistance, calculate

Homework Equations

The final impedance of the circuit
The inductance of the inductor

The Attempt at a Solution

dont want answer want to know where to start, is resistance of resistor 8.3333(R=125v/15a

Start by collecting equations relevant to the problem. You have written more of the problem statement in place of relevant equations. What equations pertain to inductors in an ac circuit?

Your resistance value is correct.
