Question

AC power in a load can be controlled by connecting option A to a SCRS in series option B to scrs in parallel options ccrs in permanent position of Sunday coming combination of two scrs in series and parallel

Answer 1

(b)AC power in a load can be controlled by connecting to SCRS in parallel.

Thyristors are for the most part utilized in AC control circuits, for example, lighting dimmers, AC motor speed controls, radiators and so forth where mains (line) voltages are utilized for load of numerous watts, or frequently kilowatts. The point of AC Control is to trigger the SCR part route through every AC cycle with the goal that the heap current through the SCR is turned off for part of the AC cycle, so limiting the normal current moving through the SCR, and subsequently the normal power conveyed to the load.
