    Magnets and simple circuits

    Magnets pull some metals, and electricity flows round a circuit to light a bulb.

    1. What magnets pull
    2. North and south poles
    3. Magnetic force through things
    4. Making a compass
    5. Electricity: safe and unsafe
    6. A simple circuit
    7. Conductors, insulators and switches

    Circuits and Ohm's law

    Current, voltage and resistance are linked, and this lets us design and fix circuits.

    1. Charge and current
    2. Potential difference
    3. Ohm's law
    4. Different components
    5. Series circuits
    6. Parallel circuits
    7. Power in circuits

    Magnets, motors and generators

    Electric currents and magnets push on each other, and that is how motors and generators work.

    1. Magnetic fields
    2. Fields around wires and coils
    3. The motor effect
    4. Electric motors
    5. Electromagnetic induction
    6. Generators and dynamos

    Electric circuits and capacitors

    Circuits follow rules about charge and energy, and capacitors store charge for later.

    1. Resistivity
    2. Kirchhoff's laws
    3. Potential dividers
    4. Electromotive force and internal resistance
    5. Capacitors
    6. Capacitors in series and parallel
    7. Charging and discharging
    8. Using capacitors
