Student Reading Activity Plug Safety Features Safety features of a plug The three pin plug has a number of safety features. The first is the fuse. The fuse prevents the appliance (kettle, oven, microwave) from being supplied with to much electricity. The fuse has a thin wire inside of it which melts if the current gets too high. Once this wire melts no more electricity can be supplied to the appliance. Learning Activity Summarise the paragraph above in no more than two sentences. Include the terms: Fuse, current, appliance, and melts.

Plenary True or False Activity When electricity is passed through the filament of a bulb it begins to glow producing a bright light. A plug contains 3 main wires- the earth, the negative, and the live. Fuses are made of a thin wire which melts if a large current is passed through it. The neutral wire carries electricity to the appliance. The insulating wire prevents electricity from escaping out of the metal wire and giving the user an electrical shock. True False
