Electrician: apprentice Study Guide
kinetic energy - Answer Energy in motion or released potential energy
potential energy - Answer stored energy due to position
Example of potential energy - Answer water behind a dam
Example of kinetic energy - Answer when water falls through a dam and is used to generate
electricity
sources of energy used to produce electricity - Answer coal, nuclear power, natural gas, oil,
wind power, solar power, and water
Energy is converted into - Answer motion, light, heat,sound, and visual outputs
unit measurement for volt - Answer V
energy efficiency ratio of power - Answer input to output
Power generating plants that produce most of electricity in the U.S. - Answer coal- fired
a battery has potential energy - Answer based on its chemical state
Reactive power - Answer measured in VAR and its power is delivered to inductive and
capacitive loads in an electrical circuit
Apparent power - Answer measured 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 - Answer physical condition
a 3 MV wind turbine costs about - Answer $5 million dollars
electricity is produced by - Answer converting potential energy directly or indirectly into
electricity
