two lamps one rated 100w at 220v and the other 200w at 220v are connected (i) in series and (ii) in parallel to the electric main supply of 220v. Find the current drawn in each case.

Answer:
In series current should be same that is not here so they can't be in series
In parallel current drawn is 1.3636 amp
Explanation:
Power = (voltage *current)
P1= (v1*i1)
100=(220*i1)
i1 =(100/220) =(5/11) amp
P2=(v2*i2)
200= (220*i2)
i2 =(200/220) =(10/11) amp
In series the current should be same so I think they can't be in series
In parallel
Current devided
So total current drawn = (i1+i2) =(5/11)+(10/11) =(15/11) = 1.3636 amp
Hope you got your ans
