Question 47
In this task, you will make and test predictions about current in a circuit.
Work in groups.
You will need (for each group): a cell (or cells) that can operate two lamps in series, a switch, lamps, an ammeter, wires and connectors.
Safety: Never connect an ammeter directly across the terminals of a cell, battery or other power supply.
Part 1
1 Connect the circuit so that the lamps and the switch are in series with the cell (or cells), as shown. Do not include the ammeter yet.
2 Copy the circuit diagram.
3 Add arrows to your circuit diagram to show the direction that electrons flow through the circuit.
