Unit of measure of current ✔Correct Answer-Ampere
Unit of measure of voltage ✔Correct Answer-Volt
Electromotive force (emf) that generates current ✔Correct Answer-Voltage
Flow of electrons in a conductor ✔Correct Answer-Current
Unit of resistance ✔Correct Answer-Ohm
Measure of difficulty to pass current through a conductor ✔Correct Answer-Resistance
a current that varies or "alternates" from one polarity to another. Current still flows from negative to
positive, but the power source changes polarity in relation to time. ✔Correct Answer-alternating
current
The current carrying capacity of a conductor, measured in amps. ✔Correct Answer-ampacity
discharge of electricity through air or gas between two conductive electrodes ✔Correct Answer-arc
device that, by means of inductance, capacitance, or resistance, singly or combination, limits the
lamp current of a fluorescent or high intensity discharge lamp ✔Correct Answer-ballast
a conductor, which may be a solid bar or pipe, normally made of aluminum or copper, used to
interconnect one or more circuits in the electrical power system ✔Correct Answer-bus
1. the ability to hold a charge, 2. the ratio of a charge put on a conductor to the corresponding
change in potential, 3. the ratio of the charge on either conductor of a capacitor to the resulting
potential difference between the conductors ✔Correct Answer-capacitance
1. negative electrode that emits electrons or gives off negative ions and toward which positive ions
move or collect in a voltaic cell or other such device, 2. the negative pole of a battery or electrolytic
cell ✔Correct Answer-cathode
device that can be used to manually open or close a circuit and to automatically open a circuit at a
preset level to prevent damage ✔Correct Answer-circuit breaker
Wire or combination of wires that can carry an electrical current. Conductors may be insulated or
bare ✔Correct Answer-conductor
test performed on a conductor to determine if it is a complete, unbroken circuit through which
current flows ✔Correct Answer-continuity test
a three-phase connection where each phase is connected in the series with the next, separated by a
phase rotation of 120 degrees. ✔Correct Answer-delta
