text: Since the current always lags the voltage by 90o in a purely inductive circuit, we can find the phase of the current by knowing the phase of the voltage or vice versa.
text: If an AC current is applied to a circuit with an inductor and a resistor, current will lag behind voltage (dependent on inductance and frequency), because the inductor is resisting changes in current.
text: If an alternating sine voltage is applied across a coil, the current will lag behind the voltage by some phase angle as shown in the picture.
text: This means then that the current flowing through the coil will still lag the voltage, but by an amount less than 90o depending upon the values of V R and V L .
text: Specifically, an ideal inductor (with no resistance) will cause the current to lag the voltage by a quarter cycle, or 90°.
