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

$10 A$ .
