7 Ahmed investigates some electrical circuits.
In his first experiment Ahmed:
• sets up the electrical circuit shown
• closes the switch and records the brightness of the lamp.
Ahmed repeats this experiment five more times.
Each time he increases the number of lamps in the circuit.
Here are his results.
