question_answer 15)

Two lamps, one rated 100 W at 220 V, and the other 60 W at 220 V, are connected in parallel to the electric mains supply. What current is drawn from the line if the supply voltage is 220 V?

Answer:

Resistance of first lamp, resistance of the second lamp, Since the two lamps are connected in parallel, the equivalent resistance is given by or Rp =  = 302.6 Current drawn from the line, i.e., I = = 0.73 A
