What curve does sinusoidal alternating current look like?

Sine curve. A sine curve is a wavy line. The image of sinusoidal alternating current is composed of different wave lines and belongs to sinusoidal curve. The current is only 1/4 per cycle, or alternating current. The image of sinusoidal alternating current can be used to judge the change and rate of magnetic flux of the coil, the time when the coil is parallel to the magnetic induction line and other information.
