Circuit Behaviour and Troubleshooting
Read the circuit clues
The crew tests simple circuits made from cells, wires, bulbs and switches. A bulb lights only when there is a complete path for the current. In a series circuit, adding more bulbs makes each bulb less bright. A flat cell, a broken bulb, a loose wire or an open switch can stop a bulb lighting. A switch controls the circuit by breaking or completing the path.
- Each bulb becomes dimmer.
- Each bulb becomes brighter.
- Only the new bulb lights.
- The bulbs stay exactly as bright.
- A loose wire connection
- A flat cell
- A broken bulb
- An open switch
Diagnose the Moonbase circuits
For each fault, identify what the crew should investigate first. Explain your reasoning using evidence from the clues.
