Question

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

1. What is the appropriate value of the fuse to be fitted in its circuit?
2. What will happen if a 13 A fuse is fitted in its circuit?

Answer 1

1. The appropriate value of the fuse to be fitted in the circuit is 2.5 A or 3 A.
2. If a 13 A 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.
