Resistance is a concept used for DC (direct currents) whereas impedance is the AC (alternating current) equivalent. Resistance is due to electrons in a conductor colliding with the ionic lattice of the conductor meaning that electrical energy is converted into heat.
What is the difference between resistance and impedance?

Putting a coil on a lathe with a magnet rotor is the correct but its almost always measured in AC before the rectifier.
http://www.learningaboutelectronics.com/Articles/What-is-impedance.phpHenry is unit of inductor. Converting into ohms means you want to calculate the inductive reactance. So, inductive reactance XL= omega x L
i.e. XL= (2 x pi x frequency) x L Ohms
L is inductance in Henry
