You know that the voltage in an inductive circuit leads the current because the Lenz' law behavior resists the buildup of the current, and it takes a finite time for an imposed voltage to force the buildup of current to its maximum.

RL Impedance

The frequency dependent impedance of an RL series circuit.
For = x10^ H = mH = microHenries
at angular frequency ω = x10^ rad/s,
frequency = x10^ Hz = kHz = MHz
and resistance R = x10^ ohms = kohms = Megohms,

the impedance is

Z = x10^ ohms = kohms = Megohms

at phase φ = degrees.
Default values will be entered for unspecified parameters, but all component values can be changed. Click outside the box after entering data to initiate the calculation.
