Ampere: A unit of measure for an electrical current; the amount of current that flows in a circuit at an electromotive force of one Volt and at a resistance of one Ohm. Abbreviated as amp.
Battery: An energy storage device made up of one or more electrolyte cells.
Circuit: A conductor or a system of conductors through which electric current flows.
Current: Flow of electricity
Direct Current - An electric current that flows in only one direction through a circuit, as from a battery
Electromagnetic Energy - Energy that travels in waves, such as ultra-violet radiation. It can be thought of as a combination of electric and magnetic energy.
Electron - A subatomic particle with a negative electric charge. Electrostatic 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." (Source: ndt-ed.org)
Energy - The ability to do work or the ability to move an object
Incandescent Light Bulb - An incandescent bulb is a type of electric light in which light is produced by a filament heated by electric current.
Induction - The process of producing an electrical or magnetic effect through the influence of a nearby magnet, electric current, or electrically charged body.
Joule - A metric unit for measuring work and energy, named after James Joule. It is equal to the work done when a one ampere current is passed through a resistance of one ohm for one second
Light - Radiant electromagnetic energy that an observer can see.
Ohm: The unit of resistance to the flow of an electric current
Photon: A particle of light that acts as an individual unit of energy
Radiant Energy: Any form of energy radiating from a source in waves Resistance
Semiconductor: Any material that has a limited capacity for conducting an electric current. Semiconductors are crystalline solids, such as silicon, that have an electrical conductivity between that of a conductor and an insulator.
Solar Energy: The radiant energy of the sun, which can be converted into other forms of energy, such as heat or electricity.
Superconductivity - The abrupt and large increase in electrical conductivity exhibited by some metals as the temperature approaches absolute zero. Switch
Thermal Energy: The total potential and kinetic energy associated with the random motions of the molecules of a material.
Voltage: The difference in electrical potential between any two conductors or between a conductor and ground. It is a measure of the electric energy per electron that electrons can acquire and/or give up as they move between the two conductors.
Volt: The volt is the International System of Units (SI) measure of electric potential or electromotive force. A potential of one volt appears across a resistance of one ohm when a current of one ampere flows through that resistance. Reduced to SI base units, 1 V = 1 kg times m2 times s-3 times A-1 (kilogram meter squared per second cubed per ampere).
Watt: A metric unit of power, usually used in electric measurements, which gives the rate at which work is done or energy used
