Inductive reactance is defined as:
Inductive Reactance = angular frequency* inductance (*Inductive reactance is often denoted by XL and angular frequency = ω, and inductance = L)
angular frequency = 2*pi*frequency
plugging back in angular frequency you can solve for Inductive Resistance.
Rms Current is found using Ohm's Law:
Rms Current = Rms Voltage / Resistance (*where the resistance is the indcutive reactance from part A)
Max current is simply:
Max current = √2 * Rms Current
