# Long description

Part (a) shows a schematic circuit with a battery, lamp and switch.

Part (b) shows the same circuit but with symbols for the components.

The battery, lamp and switch are connected together by straight lines representing wires.

The symbol for a battery is two parallel lines, one longer than the other, oriented at right angles to the wire connections. The longer line represents the positive terminal and the shorter line the negative terminal.

The symbol for a lamp is a large circle containing a cross that looks like an X.

The symbol for a switch is two small circles with a gap between them. A straight line starts at the left circle and ends at a point above the right circle, showing the switch is open. If ‘pushed down’, this line would close the switch and complete the circuit.

Both (a) and (b) show electrons flowing from the negative to the positive battery terminal, and current flowing the other way.
