And the answer is …
The slow cooker doesn’t use much electricity. It can be a cheaper way to cook food!
A vacuum cleaner will use more electricity – it has a powerful motor that needs to drag up all that dust!
Kettles use a lot of electricity to heat up the water quickly – luckily they turn off again very quickly!
Always remember: the more powerful an appliance is, the more electricity it will use – and we pay for all the electricity we use.
