A non inductive resistor takes 8A at 100 volts. What inductance of a coil of negligible resistance must be connected in series in order that this load can be supplied from a 220 volt 60 Hz mains.
Z^2 = R^2 + XL^2
XL = 2pi(frequency) L(inductance)
The Attempt at a Solution
i have solve the resistance before the coil is added.. R=12.5 ohms....
i am stuck on how to get the value of the coil since there is no given current..
