20 mA A group of electric lamps having a total power rating of 1000 watt is connected across an AC voltage 200sin 310t 60 where t in seconds gives in volts Then the rms value of the electric current radians is through source if it is known that the source emf leads current through itself by 3 alog ell A 1 10 amp 2 10 2 amp TU 3 20 amp 4 20 2 amp
