Science QSE2 Review #1

Front

What is a series circuit?

Back

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

Front

What is a parallel circuit?

Back

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

Front

What form of energy do all activities shown use?

Back

Mechanical energy is the energy associated with the motion and position of an object.

Front

What happens when a switch in a circuit is open?

Back

When a switch is open, the circuit is not closed, and no current can flow, so devices like lightbulbs will not light up.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical circuit through which current can flow.

Front

What is the role of a switch in a circuit?

Back

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

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons through a conductor.

Front

What is the difference between mechanical and electrical energy?

Back

Mechanical energy is related to the motion and position of objects, while electrical energy is related to the flow of electric charge.

Front

What happens if a lightbulb is broken in a series circuit?

Back

If a lightbulb is broken in a series circuit, the circuit is broken, and all devices in the circuit will stop working.
