100% Correct Answers 2026-2027
Updated.
Volt - Answer unit of electrical force and is roughly analogous to psi in a water pipe or hose.
volt
ampere
ohm - Answer One __________ is required to push one__________ of current across one
__________ of resistance
Voltage - Answer __________ = Current X Resistance
120 volts - Answer typical voltage limit for residential use, excluding large appliances
240 volts - Answer typical voltage limit for air conditioners, electric heaters and kitchen ranges
in residential use
2.4kV - 34.5kV - Answer typical voltage for primary distribution lines
765kV - Answer typical maximum voltage for transmission lines
Ampere - Answer measure of electrical current and is similar to the flow rate (gpm) commonly
used to measure water flow
60 - 200 amps - Answer typical household limit of amps
15 - 30 amps - Answer typical individual circuit limit of amps
Ohm - Answer standard unit of resistance to the flow of electric current and equals the
resistance of a circuit in which a force of 1 volt maintains a current of 1 amp
Watt - Answer measure of power, one kilowatt is approximately 1.33 horsepower
Ohm's Law - Answer Volts(FORCE) = Amps(CURRENT) X Ohms(RESISTANCE)
, Watts (POWER) in relation to Amperes and Voltage - Answer Watts(POWER) = Volts (FORCE) X
Amps (CURRENT)
Conductivity - Answer the capacity of a material to transmit electricity
Electrical potential - Answer condition that allows electricity to flow from one object to
another
Potential Difference - Answer difference in voltage between two points
Electrical Resistance - Answer determines how much energy is required to move electricity
along a conductive pathway
Great Conductors - Answer Aluminum, Copper & Beethoven
Poor Conductors - Answer Porcelain, Epoxy, Fiberglass and Tyga
Enviromental Factors Increasing Likelihood of Air Flashover - Answer High Humidity, High
Particulate Matter (Brushfire, Dust Storm)
Powerhouse - Answer source of most power or energy distributed throughout the United
States and includes fossil fuels, water or wind turbines and nuclear reactors
13kV - 24kV - Answer typical voltage at generation: pre-departure voltage at generating
station
transmission lines - Answer carry extra high voltage energy (100kV - 765kV) from generation
transmission substation - Answer decrease voltage from transmission to subtransmission
subtransmission lines - Answer voltages ranging from 22 kV - 161kV transmitting electricity
from transmission substation to distribution substation
distribution substation - Answer decrease voltage from subtransmission to distribution, 2.4kV
- 34.5kV
(primary) distribution lines - Answer carry electricity at 2.4kV - 34.5kV but unlike
subtransmission, ends at the user, not a substation
