| I can | Red | Amber | Green |
|---|---|---|---|
| Charge and circuit measurements | |||
| Describe charge carriers, conventional current, complete circuits and standard circuit symbols. | |||
| Connect ammeters in series and voltmeters in parallel and explain appropriate circuit measurement. | |||
| Explain current as charge flow and calculate charge, current or time. | |||
| Explain potential difference as energy per charge and calculate voltage, energy or charge. | |||
| Series and parallel | |||
| Apply series current, voltage and resistance rules to calculate circuit values. | |||
| Apply junction and branch-voltage rules and explain why parallel additions reduce total resistance. | |||
