Electric Circuits 5.6B

Front

What is an electrical conductor?

Back

An electrical conductor is a material that allows electricity to flow through it easily. Examples include metals like copper and aluminum.

Front

Which material is the best conductor of electricity?

Back

Copper is often considered the best conductor of electricity due to its high conductivity.

Front

What happens when a circuit is open?

Back

When a circuit is open, it means that the path for electricity is broken, and the circuit is 'off', preventing current from flowing.

Front

What is the role of a switch in a circuit?

Back

A switch controls the flow of electricity in a circuit by opening (turning off) or closing (turning on) the circuit.

Front

What is a battery?

Back

A battery is a device that stores chemical energy and converts it into electrical energy to power circuits.

Front

What is the purpose of a light bulb in a circuit?

Back

A light bulb converts electrical energy into light energy, allowing us to see.

Front

What is the difference between an open circuit and a closed circuit?

Back

An open circuit has a break in the path, preventing current flow, while a closed circuit has a complete path allowing current to flow.

Front

Why is copper commonly used in electrical wiring?

Back

Copper is used in electrical wiring because it is an excellent conductor of electricity, allowing efficient current flow.

Front

What does it mean for a circuit to be 'off'?

Back

A circuit is 'off' when it is open, meaning electricity cannot flow through it.

Front

What is the function of switches in a circuit with multiple components?

Back

Switches can control which components receive electricity, allowing for selective operation of devices like light bulbs.
