Homework Help: Help solving R- L Circuit

  1. Apr 4, 2016 #1
    1. The problem statement, all variables and given/known data

    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

    2. Relevant equations
    The final impedance of the circuit
    The inductance of the inductor

    3. 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.
