Why does a kettle have 13 amp fuse but a DVD player only has 3 amp fuse?

A kettle requires a 13 amp fuse because it typically draws a high amount of current (around 2-3 kW) to quickly heat water, necessitating a higher fuse rating to prevent overheating and potential hazards. In contrast, a DVD player consumes significantly less power (usually around 20-30 watts), so a lower 3 amp fuse is sufficient to protect its circuitry without the risk of overload. The fuse rating is based on the device's power requirements and the potential risk in case of a fault.
