1. The problem statement, all variables and given/known data a non inductive resistor passes a current of 20A rms, when connected to a 100v rms supply (50HZ). When connect in series with a pure inductor across a 230v supply the combination draws a current of 15A calculate impedance of the circuit, inductance of the inductor 3. The attempt at a solution R = 100v/20A = 5 ohms Z = V/I Z = 230/15 = 15.3 z = square root R^2 + X^2 Find X^2 Z^2 - R^2 = X^2 SRoot 15.3^2 - 5^2 = 14.45 ohms From what I found how do I find the inductance of the inductor. I only know one way using flux density but there is no data given on this in the question.
