Electricity is energy. In your home electricity runs the lights, appliances like toasters, the television, toys and more. Electricity travels in circuits.
Circuits need to be complete for them to work properly. This means that the circuit must go in a full loop around from the power source and back again. Circuits that are not complete will not work.
A power source can be either a cell (battery) or mains. When using more than one cell in a circuit remember that the cells all have to be facing the same way.
The electricity which reaches your home also travels in a circuit and the ‘battery’ which supplies this energy is called a power plant. The power lines (transmission wires) which carry electricity to your home are excellent electrical conductors.
Electricity is always trying to get to the ground. Like all good travellers, electricity takes short cuts whenever it can. If something that conducts electricity, i.e. YOU, gives electricity an easy path to the ground it will take it!
