Review Sheet for the Electricity and Magnetism Test
Directions: Complete each statement with the correct vocabulary word or words.
1. A(n) series circuit is a circuit with only one path for current to follow.
2. An accumulation of excess electric charge is static electricity.
3. The electric force that makes current flow in a circuit is related to the
voltage difference.
4. According to the law of conservation of charge, electric charge cannot be created or
destroyed.
5. Resistance is the result of electrons colliding with atoms as current flows in a
material.
6. Charging a balloon by rubbing it on wool is an example of charging by contact.
7. A(n) transformer can be used to change the voltage of an alternating
current.
8. A(n) magnetic pole is the region where the magnetic field of a magnet is
strongest.
9. Direct current does not change direction.
10. The properties and interactions of magnets are called magnetism.
11. The magnetic poles of atoms are aligned in a(n) magnetic domain.

second diagram is a parallel circuit because it has two or more pathways for
current.
