Three appliances are connected in parallel to the same source which provides a voltage of 220 V. A fuse connected to the source will blow if the current from the source exceeds 10 A. If the three appliances are rated at 60 W, 500 W and 1200 W at 220 V, will the fuse blow?

Given, P1=60 W, P2=1200W, P3=500W

Fuse rating = 10A


V=220V


We have, P=VI


Total power=60+1200+500=1760W


Therefore, 1760=220xI


I=8A


No, the fuse is of desired specification so it it will work properly.
