In school, you might have learned that electrons were negatively charged and protons were positive. This is not a fact of nature but a human-invented convention. It’s a fact that protons and electrons have opposite charges, but scientists could just as easily have named electrons positive and proton…

Electrical circuits keywords

Measures how much electricity is flowing around a circuit.

ammeter

The unit for current.

amp (A)

A source of electricity with a low 'energy'. Cells push electrons round a circuit.

cell

A complete loop that electricity flows around.

circuit

Something in a circuit, like a bulb, switch or motor.

component

A material that lets electricity flow through it.

conductor

The flow of electricity around a circuit.

electric current

A material that does not let electricity flow through it.

insulator

Alternating current at 230 V provided to houses, shops etc.

mains (electricity)

A source of electricity with a low energy (low voltage) used in the laboratory.

power pack

Turns electricity on or off, by closing or opening a gap in a circuit.

switch

A way of saying how much energy is transferred by electricity.

voltage

The smallest part of an element.

atom

The flow of electrons around a circuit.

electric current

Tiny particle that flows around a circuit.

electron

Thin piece of wire inside a light bulb that glows when electricity is flowing through it.

filament

A scientific way of thinking about how things happen.

model

A way of saying how difficult it is for electricity to flow through something.

resistance

A component that makes it difficult for electricity to flow.

resistor

A resistor that can be adjusted to change the amount of resistance it has.

variable resistor

A way of saying how much energy is transferred by electricity.

voltage

A circuit with two or more wires running next to each other.

parallel circuit

A circuit where there is only one loop of wire.

series circuit

The green and yellow wire in a cable or plug.

earth wire

Part of a plug that holds the cable, and stops the wires being pulled out of the pins.

cable grip

A piece of wire that melts if too much electricity flows through it.

fuse

The brown wire in a cable or plug.

live wire

The blue wire in a cable or plug.

neutral wire

When electricity flows through the body.

electric shock
