Measurements
A unit of measurement that indicates both an amount of electricity and the time it takes to travel a certain distance. One of these equals one coulomb per second.
What are amperes?
A highly conductive, reddish-brown metal. Often used as an electrical conductor in houses, buildings, and machinery.
What is copper?
A form of energy created by the movement of electrons. Can be converted into light, heat, or motion.
What is electricity?
An attraction between materials having opposite electrical charges. Most often occurs between metals.
What is magnetism?
Electricity that travels in one direction. This does not reverse the direction of flow.
What is DC?
The smallest quantitative measurement of electrical current.
What is Coulomb?
A lightweight gas that is colorless and odorless.
What is hydrogen?
The use of magnets to cause voltage in a conductor. This is the basis for most electrical generators.
What is Magnetic Induction?
Electricity that travels in one direction. This does not reverse the direction of flow.
What is a Direct Current?
Electricity that reverses direction at regularly recurring intervals of time. This switches direction 60 times per second, or 60 hertz, in the U.S.
What is AC?
A unit of frequency equal to one cycle per second. This unit of measurement is used to measure how often the direction of alternating current reverses.
What is Hertz?
A type of resistor that gives off heat and light. These are used in light bulbs.
What is a filament?
The universal truth that describes the relationships between wattage, amperage, and voltage. This theory states that one watt equals one amp times one volt.
What is Watt's Law?
Having voltage in a circuit increased or decreased by a transformer. There is no effective way to to this to DC.
What is transformed?
Hz
What is hertz?
The rate at which a device converts electrical energy into another form, such as heat or light. This is measured in watts (W).
What is power?
The outermost orbit of electrons in an atom. This can have only eight electrons.
What is the valence shell?
A measure of electrical pressure or potential. It is measured in volts (V).
What is voltage?
A conductor that directs electricity in a circuit. This is often a copper wire.
What is a path?
EMF
What is electromotive force?
A unit of measurement for the wattage or power used in or produced by a circuit. These require a change in energy to exist.
What is a watt?
A conductor that directs electricity in a circuit. This is often a copper wire.
What is a path?
The universal truth that describes the relationships between voltage, amperage, and resistance. This law states that one volt equals one amp times one ohm.
What is Ohm's Law?
The joining of two or more atoms due to electrical force. This occurs when atoms share or transfer electrons.
What is bonding?
-
What is negative?
