Volt - unit of electrical force and is roughly analogous to psi in a water pipe or hose. volt ampere ohm - One __________ is required to push one__________ of current across one __________ of resistance Voltage - __________ = Current X Resistance 120 volts - typical voltage limit for residential use, excluding large appliances 240 volts - typical voltage limit for air conditioners, electric heaters and kitchen ranges in residential use 2.4kV - 34.5kV - typical voltage for primary distribution lines 765kV - typical maximum voltage for transmission lines Ampere - measure of electrical current and is similar to the flow rate (gpm) commonly used to measure water flow 60 - 200 amps - typical household limit of amps 15 - 30 amps - typical individual circuit limit of amps Ohm - 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 - measure of power, one kilowatt is approximately 1.33 horsepower Ohm's Law - Volts(FORCE) = Amps(CURRENT) X Ohms(RESISTANCE) Watts (POWER) in relation to Amperes and Voltage - Watts(POWER) = Volts (FORCE) X Amps (CURRENT) Conductivity - the capacity of a material to transmit electricity Electrical potential - condition that allows electricity to flow from one object to another Potential Difference - difference in voltage between two points Electrical Resistance - determines how much energy is required to move electricity along a conductive pathway
