Conductors vs. Insulators/Circuits

Front

What is a conductor?

Back

A material that allows electricity to flow through it easily, such as metals like copper and aluminum.

Front

What is an insulator?

Back

A material that does not allow electricity to flow through it easily, such as rubber, glass, or plastic.

Front

What is a circuit?

Back

A closed path through which electricity flows.

Front

What is a series circuit?

Back

A circuit in which the components are connected end-to-end, so that the current flows through each component in turn.

Front

What is a parallel circuit?

Back

A circuit in which the components are connected across common points or junctions, allowing multiple paths for the current.

Front

What happens in a closed circuit?

Back

Electricity can flow freely, allowing devices to operate.

Front

What happens in an open circuit?

Back

The flow of electricity is interrupted, preventing devices from operating.

Front

What is a semiconductor?

Back

A material that can conduct electricity better than insulators but not as well as conductors, often used in electronic devices.

Front

Why are metals commonly used in electrical wiring?

Back

Because they are good conductors of electricity.

Front

What is the role of a switch in a circuit?

Back

To open or close the circuit, controlling the flow of electricity.
