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.

2. Relevant equations

Z^2 = R^2 + XL^2

R=V/I

XL = 2pi(frequency) L(inductance)

3. 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..
