Title: The electric circuitLevel: Grades 79
Description:An electrical circuit is a system. It is a path of electrical components and conductors with no breaks in it, and an energy source to make electric charges flow around the conducting path. The energy source may be cells or the ‘mains’ electricity supply.

Lesson notes• An electric circuit is a system made up of components and conductors.• Some materials that allow electric charge to flow through them are called electrical conductors.• Metals like copper, iron and steel are examples of good electrical conductors.• Electrical insulators do not allow electricity to pass through them. Plastic, wood, glass and rubber are good electrical insulators.• An electric circuit is made when the components and conductors are connected together so that the electric charge can flow through.• An energy source can be a cell, a battery or the mains electricity supply.

What do you think will happen when the switch is opened? Click on the switch and find out.
It will break the circuit and will stop the electric charge from flowing.

What do you think will happen if you remove the cell? Click on the cell and drag it away to find out.
The electric charges need an energy source to make them flow in the circuit.
Hint
An energy source gives the charge electrical energy. The source can be a cell, group of cells connected together (called a battery) or the mains electricity supply.
