As you switch on more appliances the amount of energy required to power these appliances increases. This is shown by the increased speed of the meter (rotating disc). The exhibit displays two meter readings providing information about the cost of this energy. The right hand display panel shows how many joules of energy have been used since switching on. The other display shows either the cost per hour or the quarterly cost of operating the appliances. What type of appliances require the most energy?
