Question

Two room heaters are marked 220V, 440 W and 220V, 800W respectively. If the heaters are connected
in parallel to 220V mains supply, calculate:
i).The total current drawn from the electric supply.
ii) Total energy consumed in commercial units if they operate simultaneously for 2hours.
plz give details properly

Answer 1

Explanation:

i)Total power=440+800=1240

Power=Current*Potential difference

1240=I*220

1240/220=I

5.63A=I

ii)Total energy= Current*Time

energy=5.63*2=11.26Joule
