Master the Essentials of Jobsite Safety
Ammeter - CORRECT ANSWERS >> an instrument for measuring electric current.
Amperes (A) - CORRECT ANSWERS >> The basic unit of measurement for electrical
current, represented by the letter A
Atoms - CORRECT ANSWERS >> The smallest particles to which an element may be
divided and still retain the properties of the element.
Battery - CORRECT ANSWERS >> A DC voltage source consisting of two or more cells
that convert chemical energy to electrical energy
Charge - CORRECT ANSWERS >> A quantity of electricity that is either positive or
negative.
Circuit - CORRECT ANSWERS >> A complete path for current flow
Conductors - CORRECT ANSWERS >> Materials through which it is relatively easy to
maintain an electrical current
Coulomb - CORRECT ANSWERS >> A unit of electrical charge equal to 6.25 x 1018
electrons( or 6.25 quintillion electrons). A coulomb is the common unit of quantity used
for specifying the size of a given charge.
Current - CORRECT ANSWERS >> The movement, or flow, of electrons in a circuit.
Current (I) is measured in amperes
Electrons - CORRECT ANSWERS >> Negatively charged particles That orbit the
nucleus of an atom
Insulator - CORRECT ANSWERS >> A material through which it is difficult to conduct
an electric current.
Joule (J) - CORRECT ANSWERS >> A unit of measurement for doing work,
represented by the letter J. one joule is equal to one newton-meter (Nm).
Kilo - CORRECT ANSWERS >> A prefix used to indicate one thousands , one kilowatt
is equal to one thousand watts
Matter - CORRECT ANSWERS >> any substance that has mass and occupies space
Mega - CORRECT ANSWERS >> A prefix used to indicate one million; for example,
one mega watt is equal to one million watts
