A TV set consumes an electric power of 230 watts and runs on 230 volts mains supply. The correct fuse for this TV set is :
(a) 5 A (b) 3 A (c) 1 A (d) 2 A
Power = 230 W
Voltage = 230 V
Power = VI
where I is the current
I =
hence
I = = 1A
hence fuse should be just greater than this current,
So the answer is 2A(d)
