What is an open circuit?

Back

An open circuit is a type of circuit that has a broken path, preventing current from flowing through it.

Front

What is static electricity?

Back

Static electricity is the build-up of electric charge on the surface of objects, which can cause them to attract or repel each other.

How does a comb lift paper when rubbed on hair?

Back

The comb can lift the paper because the paper becomes electrically charged and is attracted to the comb.

Front

What happens to a circuit when it is closed?

Back

In a closed circuit, the path is complete, allowing electric current to flow.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical circuit through which current can flow.

Front

What is the effect of adding heat to a solid?

Back

Adding heat to a solid can cause it to change into a liquid, demonstrating a phase change.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where there are multiple paths for current to flow.

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet that is created by electric current flowing through a coil of wire.

Front

What is the role of a switch in a circuit?

Back

A switch is used to open or close a circuit, controlling the flow of electricity.

Front

What is the difference between static electricity and current electricity?

Back

Static electricity is the build-up of charge, while current electricity is the flow of electric charge through a conductor.
