Physical Science Electricity Test

A light bulb represents a device that converts electrical energy into light energy.

A closed circuit is a complete, unbroken path through which electric charges can flow.

An open circuit is a broken path that prevents electric charges from flowing.

The light bulb is off because it needs a complete path for electrons to flow.

A nail is the best electrical conductor among the options provided.

An electric circuit is a complete, unbroken path that allows electric charges to flow.

An insulator is a material that does not allow electric charges to flow easily.

Copper is an example of a good conductor.

The light bulb lights up because it is part of a complete circuit.

Electric current is the flow of electric charge through a conductor.
