The list of household electrical appliances categorized according to their power consumption and what fuse they will use are:
<u>3A Fuse </u>
- A table lamp,
- Computer
- Blender,

What is a fuse value?</h3>
A fuse rating is the amount of current required to blow (break) the fuse. When a fuse blows, it disconnects power from an electrical system.
The fuse rating is generally printed on the fuse itself. The fuse rating is often expressed in 'amps,' which is the standard measurement for electrical current.
<h3>Why are electrical fuses important?</h3>
If an appliance malfunction results in an excessive current flow, the fuse shuts off the circuit.
If something goes wrong, this safeguards both the wiring and the appliance. A wire that melts easily is within the fuse.
