- The circuit is a simple series circuit.
- Current flows from the positive terminal of the battery, through the fuse, then through the switch, then through lamp R1, then through lamp R2, and finally back to the negative terminal of the battery.
- Since the lamps are connected in series, the same current flows through both R1 and R2.
- If either lamp burns out or the switch is opened, the entire circuit is broken and both lamps will turn off.
- The total voltage of the battery is divided between the two lamps.
Parent Tip: Review the logic above to help your child master the concept of series circuit parts.
