- Introduce a model to associate energy transfer with voltage,
eg the 'almost Monopoly' or 'pocket money' analogy, where pupils are given money that has to be spent around the circuit before they can return. Pupils are the current, the cell is the source of the money ('GO'), which is the energy. The cells or voltage permit them to move. If they go through more cells, they pick up more money; and as they go round the circuit, they have to pay out equal amounts per device (assuming identical devices). As an analogy of resistance, money could be paid out in proportion to 'number of hotels', or use a similar rule from Monopoly. Note the shortcoming in the analogy - in Monopoly circuits all the money does not have to be spent.
- An alternative model is the 'up-and-down' ski-lift. Chairs are the 'current/charge' which the 'voltage' of the motor causes to move (flow). Skiers are the 'energy', climbing on at the motor-house and getting off at suitable places ('devices') around the ski-lift circuit.
