Circuits, Conductors, and Insulators

Front

What is a conductor?

Back

A conductor is a material that allows thermal and electrical energy to pass through easily. Examples include metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that does not allow thermal and electrical energy to pass through easily. Examples include rubber, plastic, and wood.

Front

What is an open circuit?

Back

An open circuit is a circuit that is incomplete or broken, preventing the flow of electricity.

Front

What is a closed circuit?

Back

A closed circuit is a complete circuit that allows electricity to flow.

Front

What is resistance in a circuit?

Back

Resistance is a measure of how much a material opposes the flow of electric current. It is measured in ohms.

Front

What materials are good conductors?

Back

Good conductors include metals like copper, aluminum, and silver.

Front

What materials are good insulators?

Back

Good insulators include rubber, glass, and dry wood.

Front

What happens in a circuit when a switch is open?

Back

When a switch is open, the circuit is incomplete, and electricity cannot flow.

Front

What happens in a circuit when a switch is closed?

Back

When a switch is closed, the circuit is complete, allowing electricity to flow.

Front

What is a parallel circuit?

Back

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