How much do these appliances cost to run?
Do you know how much of your home's electricity bill goes to make cups of tea or to wash your clothes?
Sort these electrical goods by how much they cost to run.
The figures in our activity refer to how much it would cost, on average, to use an appliance over the course of an hour. Bear in mind you wouldn’t use some of these appliances, like the kettle, continuously for an hour at that particular wattage.
Some of these appliances, (for example, a washing machine) don't use a constant amount of power over a whole cycle, so we have given you an average of their power use.
Answers from lowest to highest:
Fridge; games console; electric radiator; kettle; washing machine; electric shower.

What are electric shocks? How do I avoid them?
Electricity is amazingly useful, but can also be incredibly dangerous.
If you touch something with electricity running through it, it will pass through your body before you have any time to react. If you touch something at a high voltage, you will get an electric shock. In some cases, you will feel a small tingle. However, the electrical supply in your home is extremely dangerous - the shock can be enough to stop a person’s heart. You should never go near or touch an exposed wire in your house or use appliances that have frayed or exposed wires.
