Circuits, Conductors, and Insulators

Front

What is a circuit?

Back

A circuit is a closed pathway through which electrical current flows.

Front

What is a conductor?

Back

A conductor is a material that allows thermal and electrical energy to pass through easily.

Front

What is an insulator?

Back

An insulator is a material in which electrons are not able to move easily.

Front

What role does a battery play in a circuit?

Back

A battery provides the electrical energy needed to complete the circuit.

Front

Can water be considered a conductor?

Back

Yes, water is a conductor because it allows electrical current to flow through it.

Front

What are some common examples of conductors?

Back

Common examples of conductors include metals like copper, aluminum, and gold.

Front

What are some common examples of insulators?

Back

Common examples of insulators include rubber, glass, and plastic.

Front

How does temperature affect the conductivity of materials?

Back

Generally, as temperature increases, the conductivity of conductors increases, while the conductivity of insulators decreases.

Front

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, components are connected end-to-end, so current flows through each component in turn. In a parallel circuit, components are connected across common points, allowing current to flow through multiple paths.

Front

What happens if there is a break in a circuit?

Back

If there is a break in a circuit, the flow of electrical current is interrupted, and the circuit will not function.
