In an AC network, the load connected is (10 + j10). The phase relation between the voltage applied and the current through the load is:
Sudden changes of load on synchronous motors may sometimes set up oscillations that are superimposed upon the normal rotation, resulting in periodic variations of a very low frequency in speed. This effect is known as hunting or phase-swinging.
