Questions and Correct Answers/ Latest
Update / Already Graded
War of the currents
Ans: AC vs DC. Thomas Edison favored DC while George
Westinghouse and Nikola Tesla supported AC. AC transmission
won due to the ability to convert AC voltages from higher to
lower voltages using transformers. Less power line losses and
can be transported longer distances.
power plant
Ans: converts the electrical energy (coal, oil, gas) or potential
energy (water, nuclear) into electrical energy
transmission and distribution lines
Ans: transport and distribute electrical energy
substations with switch gear
Ans: this transforms voltages, provides protection, form node
points

loads
Ans: consume energy
fossil and nuclear power plants
Ans: thermal energy converted to high pressure high steam
that drives a turbine which is connected to a generator
hydroelectric power plants
Ans: the water falling to a lower elevation drives the turbine
generator set
extra high voltage line
Ans: transformers increase generator voltage to 500kV and
supply EHV which carries energy to a substation far away. They
interconnect the power plant with substations in load centers.
The max length is 400-500 miles. EHV substations reduce
voltage to high voltage.
high voltage line
Ans: high voltage lines interconnect substations in different
load centers. high voltage lines are (115kv to 230kv) and max
length is 100-200 miles.
