An electric kettle rated as 1200 W at 220 V and a toaster rated at 1000 W at 220 V are both
An electric kettle rated as 1200 W at 220 V and a toaster rated at 1000 W at 220 V are both connected in parallel to a source of 220 V. If the fuse connected to the source blows when the current exceeds 9.0 A, can both appliances be used at the same time ? Illustrate your answer with calculations.

P1=1200W, P2=1000W
V=220V Fuse rating=9A
We know, P=VI
Total current required, I=P/V =(P1+P2)/V =(1200+1000)/220 =10A
If both the appliances are switched on together, the fuse will get burnt. So, both the appliance cannot be used at same time.
