Relier Pairs Central Heating ModelVersion en ligne The central heating model helps to explain what happens in an electric circuit. Match up the statements for the model to what goes on in the circuit. par Gideon Williams 1 Water flows through the pipes 2 All the water stays in the pipes 3 The water has most energy when it has just left the boiler, and least energy when it returns to the boiler 4 Pipes let water flow through them 5 Adding more radiators will make it harder for water to flow around the circuit 6 The boiler transfers heat energy to the water 7 If you measured the amount of water flowing, you would get the same answer everywhere in the central heating system 8 The pump pushes the water through the pipes 9 In the radiator, energy is transferred from the hot water to the room by heating Charges flow through the wires Adding more bulbs will make it more difficult for the charges to flow around the circuit The cell transfers energy to the charges The cell pushes the charges around the circuit Wires let charges flow through them All the charges stay in the wires If you measured the current flowing, you would get the same reading everywhere in the circuit The charges have the most energy when they have just left the cell, and the least energy when they return to the cell In the bulb, electrical energy is transferred to the surroundings by light and heating
