Question

reason for this answer? ......​

Answer 1

We know that

Power = work done / time  taken

           = potential x charge / time taken

           = potential x current

         i.e. current = power / potential

                            = 5 KW / 200 V

                            = 5000 / 200

                            = 25 A

Since it is the greater than 8A as rated in the fuse.

Therefore can't be used.

Answer 2

Hiii Pagal Priyansh...!✌

Given-:
Power = 5kW = 5000 W
Potential = 200 V

We know that
Power = Potential * Current

5000 = 200 * I
I = 25 A

But the fuse is rated 8 A and so it can not be used with this electrical appliance because after the current exceeds 8 A current fuse wise will melt and break the circuit.

Hope this helps!
