A sinusoidally driven circuit containing an inductor and a resistor has a response given by

where
is the peak amplitude,
is the driving angular frequency, and
is a phase shift from the phase of the source. The (complex) current can be found as

where Z is the total impedance,
is the permittivity of free space, L is the inductance, R is the resistance, and
is the angular frequency. The phase difference is then

with peak current given by


(1)
where




(2)
where Z is the total impedance,



(3)
with peak current given by

(4)
