Chapter 8: Electricity and Magnetism

Front

What is an open circuit?

Back

An open circuit is a type of electrical circuit where the path is broken, preventing the flow of electric current. For example, when a lightbulb is off, it indicates an open circuit.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical circuit that allows current to flow. For example, when a lightbulb is lit, it indicates a closed circuit.

Front

What are the two types of electric charges?

Back

The two types of electric charges are Positive and Negative.

Front

What happens when a magnet is cut in half?

Back

When a magnet is cut in half, each half will have two poles: a North pole and a South pole.

Front

What is electric current?

Back

Electric current is the flow of electric charge, typically carried by electrons in a conductor.

Front

What is the role of a lightbulb in a circuit?

Back

A lightbulb converts electrical energy into light energy, indicating whether the circuit is open or closed.

Front

What is a conductor?

Back

A conductor is a material that allows electric current to flow through it easily, such as copper or aluminum.

Front

What is an insulator?

Back

An insulator is a material that resists the flow of electric current, such as rubber or glass.

Front

What is static electricity?

Back

Static electricity is the buildup of electric charge on the surface of objects, often caused by friction.

Front

What is a magnet?

Back

A magnet is an object that produces a magnetic field, attracting certain metals like iron.
