Electricity

Battery

A device that converts chemical energy to electrical energy, it is made of cells. Battery. A battery stores chemical energy and transforms it into electricity to power various devices.

Conductor

A material that lets electricity pass through easily. Conductor. A conductor is a substance that allows electricity to flow through it with minimal resistance.

Electric circuit

A closed loop through which electric current can flow. Electric circuit. An electric circuit is a path that allows electricity to move from a power source through wires to devices and back again.

Electric current

A flow of electric charge, it is measured in amperes A. Electric current. It is like the flow of water through a pipe, but instead of water, it's electricity moving through wires.

Electric resistance

The ability of a material to slow or stop the flow of electric current. Electric resistance. Electric resistance is how much a material opposes the flow of electricity through it.

Insulator

A material that does not let electricity pass through easily. Insulator. An insulator is a substance that prevents the flow of electric current.

Law of conservation of charge

States that charge can move from one object to another but cannot be created or destroyed. Law of conservation of charge. This law means that the total charge in a closed system always stays the same.

Parallel circuit

A circuit in which current can flow through more than one path. Parallel circuit. A parallel circuit is a type of electrical circuit where components are connected alongside each other, allowing current to divide and flow through multiple paths.

Series circuit

A circuit in which there is a single path for current to follow. Series circuit. In a series circuit, electricity flows along one continuous path through all the components one after the other.

Static electricity

The electric charge that builds up on an object. Static electricity. It is the build-up of electrical charges on the surface of a material.

Voltage

The difference in electrical potential energy between two points in a circuit. Voltage. Voltage is like the pressure that pushes electrical charges through a circuit.
