A 1.25kW heater works on a 220V mains supply. What current rating would a suitable fuse have? a) 2A b) 5A c) 10A d) 13A

Answer:

The correct option is c) 10A

Explanation:

We need a fuse with a current capacity somewhat higher than the devices. So, 10 A is a little more than the device’s current draw of 5.68 A.
