Released STAAR Questions 5.6B Circuits and Electricity

Front

What is a circuit?

Back

A circuit is a closed path through which electric current flows.

Front

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

Back

In a series circuit, all components are connected in a single path, so if one component fails, the entire circuit stops working. In a parallel circuit, components are connected across common points, so if one component fails, the others can still function.

Front

What happens when a lightbulb burns out in a series circuit?

Back

The entire circuit stops working because the path for the electric current is broken.

Front

What happens when a lightbulb burns out in a parallel circuit?

Back

The other lightbulbs continue to work because there are multiple paths for the electric current.

Front

What is a power source in a circuit?

Back

A power source provides the energy needed for the circuit to function, such as a battery or a plug connected to an outlet.

Front

What is a switch in a circuit?

Back

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

Front

What is a fuse?

Back

A fuse is a safety device in a circuit that protects against overload by breaking the circuit if too much current flows.

Front

What is the role of wires in a circuit?

Back

Wires connect different components of a circuit and allow electric current to flow between them.

Front

What is solar energy?

Back

Solar energy is energy from the sun that can be converted into electricity using solar panels.

Front

What is the purpose of a buzzer in a circuit?

Back

A buzzer is an output device that produces sound when electric current passes through it.
