6.1
Circuits, conductors and insulators
Complete circuits, current as a flow of charge, circuit symbols, switches, and conductors and insulators.
6.2
Current in series and parallel circuits
Measuring current with an ammeter, and how current behaves in series circuits and in parallel branches.
6.3
Potential difference and resistance
Potential difference measured in volts, voltmeters, cell and lamp ratings, and resistance in ohms.
6.4
Static electricity
Charging by rubbing, attraction and repulsion between charges, electric fields and sparks.

What this unit covers
Mapped to the KS3 national curriculum (Physics: electricity and electromagnetism).
| Programme of study | Lesson |
|---|---|
| electric current, measured in amperes, in circuits; current as flow of charge | 6.1, 6.2 |
| series and parallel circuits; currents add where branches meet | 6.2 |
| potential difference, measured in volts; battery and bulb ratings | 6.3 |
| resistance, measured in ohms, as the ratio of potential difference to current | 6.3 |
| differences in resistance between conducting and insulating components | 6.1, 6.3 |
| separation of positive or negative charges when objects are rubbed together: transfer of electrons; forces between charged objects | 6.4 |
| the idea of an electric field, forces acting across the space between objects not in contact | 6.4 |
