Energy and Circuits

Front

What is an electric circuit?

Back

An electric circuit is a closed loop that allows electric current to flow, consisting of a power source, conductors, and a load (like a lightbulb).

Front

What is a complete circuit?

Back

A complete circuit is one where the path for electric current is unbroken, allowing electricity to flow and power devices.

Front

What happens in a series circuit when one component fails?

Back

In a series circuit, if one component fails (like a burned-out bulb), the entire circuit stops working because the path is broken.

Front

What happens in a parallel circuit when one component fails?

Back

In a parallel circuit, if one component fails, the other components can still operate because they have separate paths for current.

Front

What is a switch in an electric circuit?

Back

A switch is a device that can open or close a circuit, controlling the flow of electricity.

Front

What is the role of a battery in a circuit?

Back

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

Front

What is a lightbulb in an electric circuit?

Back

A lightbulb is a device that converts electrical energy into light energy when current flows through it.

Front

What is the difference between conductors and insulators?

Back

Conductors allow electricity to flow easily (like copper), while insulators resist the flow of electricity (like rubber).

Front

What is the function of wires in a circuit?

Back

Wires connect different components of a circuit, allowing electric current to flow between them.

Front

What is an open circuit?

Back

An open circuit is one where the path for electric current is broken, preventing electricity from flowing.
