SSC JE Electrical 2019 with solution SET-1 At f = _____R – L – C series circuit operates at unity power factor 1/RC 1 ⁄ RLC 1/2π√LC 1 ⁄ LC 1/RC 1 ⁄ RLC 1/2π√LC 1 ⁄ LC ANSWER DOWNLOAD EXAMIANS APP
SSC JE Electrical 2019 with solution SET-1 Hunting occurs in a/an motor Synchronous DC series DC shunt Induction Synchronous DC series DC shunt Induction ANSWER EXPLANATION DOWNLOAD EXAMIANS APP 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.
