ELECTRICITY

We can get electricity from a battery or the mains.
Electricity will flow around a circuit like water through a pipe. This is the current. Instead of water there are charged particles called electrons flowing around the wires. Current is the flow of charge.

Electricity travels from the power source, such as a battery, round a series of conductors (the circuit) back to the power source.

If there is a gap in the circuit - no electricity will flow.

We draw a circuit diagram which uses symbols instead of pictures.
Set up this circuit using the boards.

Set up a circuit using 2 batteries and 1 bulb.
Draw the circuit diagram. What happened to the bulb? What happens if you turn 1 of the batteries around?

Copy and complete the following statements by selecting the correct word from the box.
can can’t negative positive energy complete open closed For a current to flow there must be a ………….circuit. For a current to flow switches must be ………… If there is no gap in a circuit the current ………. Flow. For a circuit to work 2 cells must be connected positive to …… A battery or power pack is a source of electrical ………..
