Question

A capacitor of unknown value and inductor of 0.1H and a resistor of 10 ohms are connected in series to a 220 v 50 hz ac source .It is found that power factor is unity .Find the capacitance of capacitor and max amplitude of current.

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
