A device that produces electric charge and is used in electrostatic experiments.

An electrical property; it can either be positive or negative.

The invisible field around a charged object that causes another charged object to experience a force.

Moving electric charge

Combined science

Linking current, potential difference and resistance

Resistance of a wire at a constant temperature

Analysing series circuits: including complex calculations

Adding components to a parallel circuit

Analysing parallel circuits: including complex calculations

In the Circuit components unit, they will build on this knowledge to learn how the resistance of filament lamps and diodes change with current and about the properties and applications of light dependent resistors and thermistors.

In the Resistance and parallel circuits unit, pupils learnt about electrical resistance and parallel electric circuits.

This unit covers static electricity, electric fields, and current flow in series and parallel circuits. It explains current, resistance, and potential difference relationships and explores diodes, thermistors, and LDRs. The focus is on calculations, experiments, and accurate measurements.

Electric fields and circuit calculations

the voltage or a measure of the ‘push’ on electrons in a circuit

a measure of how difficult it is for current to flow in a circuit

a measure of the amount of charge passing a given point in one second

the variable that the person doing the experiment changes

the variable that is measured; it changes as a result of varying the independent variable

a variable that needs to be kept the same to allow a fair test to be carried out

a type of error that affects results in an unpredictable way

describes the relationship between two variables if both increase in the same proportion as each other

Electrical current is the amount of charge flowing past a given point in one second.

A series circuit is an electrical circuit with a single loop.

P.d is a measure of the push an electric field gives to charges.

Resistance is a property of a material that prevents the flow of current.

an electrical property; it can either be positive or negative

a circuit with separate branches connected to the battery

the invisible field around a charged object that causes other charges to experience a force

a separate series loop in a parallel circuit

a property of materials that makes it harder for current to flow

a measure of how 'hard' an electric field can push charge

a type of circuit in which there are two or more separate branches
