A cooler of 1500 W, 200 V and a fan of 500 W, 200 V are to be used from a household supply. The rating of the fuse to be used is?

When a cooler of

1500 W,

200 V

and a fan of

500

W

and

200

V

are to be used from a household supply then the rating of the fuse to be used is

10 A

.
It is given that the power and voltage of the cooler and fan is

1500 W,

200 V

and

500

W,

200

V

respectively.
The total power of the household is equal to the sum of the individual powers. Therefore,

P = P_{1} + P_{2}

\Rightarrow P = 1500 + 500

\Rightarrow P = 2000 W

The current drawn from the supply is given as

I = \frac{P}{V}

\Rightarrow I = \frac{2000}{200}

\Rightarrow I = 10 A

Hence, the rating of the fuse is

10 A
