Three appliances are connected in parallel to the same source which provides a voltage of 220 V.

Hi, I have a question and I hope anyone could answer it:

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 60 W, 500 W and 1200 W at 220 V, will the fuse blow?

    2. P1=60 W, P2=1200W, P3=500W 

      Fuse rating = 10A V=220V We have, 

      P=VI 

      Total power=60+1200+500=1760W 

      Therefore, 1760=220 x I I=8 A 

      The required current is 8A and fuse rating is 10A. So, all the appliances will work normally and the fuse will not blow.
