SUMMARY

The discussion focuses on calculating inductance in an R-L circuit where a resistive load draws 15A at 125V and is connected to a 230V supply. The resistance of the resistor is confirmed to be 8.3333 ohms, calculated using Ohm's Law (R = V/I). Participants emphasize the importance of understanding the final impedance of the circuit and the relevant equations for inductors in AC circuits to solve the problem effectively.

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
