Question 108

An electrical appliance is connected to a mains supply. A 13 A fuse is installed to protect the appliance and user.

In which wire is the fuse positioned, and what is its action when the current becomes too high?

Live wire; melts and disconnects the circuit

Live wire; limits the current to exactly $A13\text{ A}$

Neutral wire; melts and disconnects the circuit

Earth wire; diverts the excess current to the ground
