Electricity and Magnetism Review

Front

What subatomic particle causes magnetism in an atom?

Back

Electrons are the subatomic particles that cause magnetism in an atom.

Front

What is static electricity?

Back

Static electricity is the build-up of electric charge on the surface of objects, often resulting in a spark or shock, such as a lightning strike during a storm.

Front

What is a closed circuit?

Back

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

Front

What happens to the current when more light bulbs are added to a series circuit?

Back

The current slows down and the lights dim lower when more light bulbs are added to a series circuit.

Front

What does the symbol for a switch look like?

Back

The symbol for a switch is typically represented by a break in the line with a small lever or dot.

Front

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

Back

In a series circuit, components are connected end-to-end, so the current flows through each component one after another. In a parallel circuit, components are connected across common points, allowing current to flow through multiple paths.

Front

What is an insulator?

Back

An insulator is a material that does not allow electric current to flow through it easily, such as rubber or glass.

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 the function of a resistor in a circuit?

Back

A resistor is used to limit the flow of electric current in a circuit.

Front

What is magnetism?

Back

Magnetism is a force that can attract or repel certain materials, primarily due to the motion of electrons.
