Homework Statement
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
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.
