Question

A capacitor of 10 μF has a potential difference of 40 volts across it. If it is discharged in 0.2 second, the average current during discharge is(a) 2 mA(b) 4 mA(c) 1 mA(d) 0.5 mA

Answer 1

Three- phase AC Regulators

There are many types of circuits used for the three-phase ac regulators (ac to ac voltage converters), unlike single-phase ones. The three-phase loads (balanced) are connected in star or delta. Two thyristors connected back to back, or a triac, is used for each phase in most of the circuits as described. Two circuits are first taken up, both with balanced resistive (R) load
