Cost of electricity

Filed Under (year 11) by griggans on 31-10-2007



We pay for electrricity in units. 1 unit = 1 kilowatt-hour (Kwh)

If an appliance has a power rating of 1kW and is used for 1 hour it will use 1 unit.

A unit costs about 10p.

On your electricity bill it will have the current reading and the previous reading. How can you check that you are paying the right amount?
