Question

A vacuum cleaner draws a current of 2 A from the mains supply.

(a) What is the appropriate value of the fuse to be fitted in its circuit ?

(b) What will happen if a 13 A fuse is fitted in its circuit ?

Answer 1

(a) The appropriate value of the fuse to be fitted in the circuit is 2.5A or 3A.

(b) If a 13A fuse is fitted in the circuit, it will not protect the vacuum cleaner against the very high current flowing through it. This may damage the appliance.
