Inductive Circuit Waveform. V t 325 sin 314t 30 o and l 2 2h. The angular velocity of an ac circuit is another way of expressing its frequency in units of electrical radians per second instead of cycles per second.
Therefore the current lags the applied voltage by 90 in a purely inductive circuit. L is the inductance of the coil in henry. Phasor diagram and waveform of pure inductive circuit.
Xl ωl 2πfl since ω 2πf where xl is the inductive reactance in ohm s.
Inductive reactance increases with increasing frequency. The angular velocity of an ac circuit is another way of expressing its frequency in units of electrical radians per second instead of cycles per second. In an inductive circuit the inductor is placed across the ac voltage supply. Most ac circuits contain some type of inductance in which case the current waveform lags the voltage or reaches its peak slightly after the voltage waveform.
