'A fuse is rated 8 A'. Can it be used with an electrical appliance of rating 5 kW, 200 V ?

Explanation

Given P = 5 KW = 5000 W, V = 200 V
Current drawn `i =(P )/(V ) = ( 5000W)/( 200 V ) = 25 A`
Since the appliance when in use will draw 25 A current, the fuse rated 8 A cannot be used because it will blow off as the current will exceed 8A and the circuit will break.
