In a large building, there are 15 bulbs of 40 W, 5 bulbs of 100 W, 5 fans of 80 W and 1 heater of 1 kW. The voltage of electric mains is 220 V. The minimum capacity fo the main fuse of the building will be :

A

`8A`

B

`10A`

C

`12A`

D

`14A`

Text Solution

Verified by Experts

The correct Answer is:
C
(c) Total power consumed by electrical appliances in the building, `P_(t otal) = 2500 W`
`Watt = Volt xx ampere`
`rArr 2500 = V xx I`
`rArr 2500 = 220I`
`rArr I = 2500/220 = 11.36 ~~ 12A`
(minimum capacity of main fuse).
