Electricity and Circuits (STAAR released questions)

Front

What is electricity?

Back

Electricity is a form of energy resulting from the flow of electric charge, typically through wires.

Front

What is a circuit?

Back

A circuit is a closed loop that allows electric current to flow, consisting of a power source, conductors, and a load.

Front

What is a series circuit?

Back

A series circuit is a type of circuit where components are connected end-to-end, so the current flows through each component in turn.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where components are connected across common points, allowing current to flow through multiple paths.

Front

What happens when a circuit is incomplete?

Back

When a circuit is incomplete, the flow of electric current stops, and devices connected to the circuit will not work.

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 a switch?

Back

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

Front

What is resistance in a circuit?

Back

Resistance is a measure of how much a material opposes the flow of electric current, affecting how much current flows in a circuit.

Front

What is a light bulb?

Back

A light bulb is a device that converts electrical energy into light energy when current passes through it.

Front

What is mechanical energy?

Back

Mechanical energy is the energy associated with the motion and position of an object, often produced by machines.
