Across
- 2. This force is called electromotive force, or EMF.
- 6. All of these sources of electricity convert something called potential energy to kinetic energy.
- 7. Field When energy from a power source such as a battery is applied to a circuit, making the electrons flow through a conductor, a new type of field is developed around the wire.
- 9. Term that describes the forces that oppose the flow of electron current in a conductor.
- 11. The flow of electrons is measured in units called amperes.
- 12. Charge Electrons are the smallest and lightest of the particles in an atom. Protons are much larger and heavier than electrons.
- 13. Models Describe the basic structure of an atom.
- 14. Law Important mathematical relationship between voltage, current and resistance in electricity.
Down
- 1. Circuit Some electrons go through one load and some go through the other load, all at the same time.
- 3. Current The direction of current is switching back and forth 60 times each second.
- 4. Circuit There is only one path for the electrons to take between any two points in this circuit.
- 5. In 1820, a Danish scientist named Hans Oersted discovered that a magnetic compass could be deflected from its resting position if a wire carrying electric current were placed near the compass.
- 7. Naturally occurring force that exists all around us.
- 8. Current Either way the battery is connected to the circuit, current can only flow in one direction.
- 10. Any material that is composed of more than one type of atom is called a compound.
