Question

A TV set consumes an electric power of 230 watts and runs on 230 volts main supply the correct fuse for this TV set is

Answer 1

Hello Friend

Power = 230 watts

Voltage ( Potential Difference ) = 230

( Fuse rating ) = ?

$current \: = \frac{power}{potential \: difference} \\ \\ \: = \frac{230}{230}$ × 1.25 A

= 1.25 A

Value of Fuse rating is taken in integers i.e fuse rating = 2A

Answer 2

given power= 230 watt
potential difference = 230 volts

fuse rating =( power /pot. diff)*1.25 ampere
= (230/230) *1.25 = 1.25 ampere
but it's value always taken as integer

that's why answer will be 2 ampere
