Circuit Diagrams: Lamp
Circuit diagrams can be used to show a circuit. Circuit diagrams are made up of a combination of symbols.

Battery, bulb, wires & switch
- This is a circuit diagram that has 1.5 V battery.
- The switch is on and the bulb lights up.

Increasing the voltage
- When another 1.5 V battery is added, the bulb becomes brighter.
- The bulb gets brighter because there is a higher voltage.
- Greater voltage makes more current flow around the circuit.

Too much voltage
- If there is too much voltage, the current gets too high.
- The wire in the bulb could melt if the current gets too high.
- The wire melting results in the bulb blowing.
