Circuits, electricity, and magnetism

Front

What happens when an electric current flows in a wire?

Back

A magnetic field is created.

Front

How are electric and magnetic forces related?

Back

Both the electric and magnetic forces are caused by the motion of charged particles such as electrons.

Front

What type of circuit allows some lights to turn off while others remain lit?

Back

Parallel circuits allow some lights to turn off while others remain lit.

Front

Why does current flowing through a wire create a magnetic field?

Back

Because magnetic force is another aspect of electrical force.

Front

What is a series circuit?

Back

A circuit in which components are connected end-to-end, so that the current flows through each component in turn.

Front

What is a parallel circuit?

Back

A circuit in which components are connected across common points or junctions, allowing multiple paths for current.

Front

What is the role of electrons in electricity?

Back

Electrons are charged particles that flow through a conductor to create electric current.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

Front

What is the unit of electric current?

Back

The unit of electric current is the Ampere (A).

Front

What is the unit of voltage?

Back

The unit of voltage is the Volt (V).
