5.6B STAAR Released Questions

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

Switches are used to open or close a circuit, controlling the flow of electricity.

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

When a switch is closed, the circuit is complete, and electricity can flow.

A lightbulb is a device that converts electrical energy into light energy.

An LED (Light Emitting Diode) is a semiconductor device that emits light when current flows through it.

Lights are 'on' when electricity is flowing through the circuit and powering the lightbulbs.

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

A series circuit is a type of circuit where all components are connected in a single path.

You can determine which switches can be open by analyzing the circuit's layout and the connections.
