ELECTRICIAN APPRENTICE
CORRECT 100%
kinetic energy - ANSWEREnergy in motion or released potential energy
potential energy - ANSWERstored energy due to position
Example of potential energy - ANSWERwater behind a dam
a battery has potential energy - ANSWERbased on its chemical state
Reactive power - ANSWERmeasured in VAR and its power is delivered to inductive
and capacitive loads in an electrical circuit
Apparent power - ANSWERmeasured in VA and is the calculated product of voltage
and current in a circuit without regard to the phase shift
a compressed spring has potential energy due to its - ANSWERphysical condition
Example of kinetic energy - ANSWERwhen water falls through a dam and is used to
generate electricity
sources of energy used to produce electricity - ANSWERcoal, nuclear power, natural
gas, oil, wind power, solar power, and water
Energy is converted into - ANSWERmotion, light, heat,sound, and visual outputs
unit measurement for volt - ANSWERV
energy efficiency ratio of power - ANSWERinput to output

electricity is produced by - ANSWERconverting potential energy directly or indirectly
into electricity
difference between voltage E and volts V - ANSWERvoltage E is amount of electrical
pressure in a circuit. Volt V is the measure of voltage
two sources of voltage - ANSWERDirect DC and alternating AC
megohmeter - ANSWERvoltages in the range of 50 to 5000 volts and test for
insulation damage to conductors or windings
