2nd year, Lever1 Lesson11 Comparing
Direct Current to Alternating Current
? voltages are better for transmitting electricity over long distances. - correct
answer-Higher
A higher voltage can be used to transmit the same amount of power at a(n) ? current
value. - correct answer-
AC is raised from one level of voltage for transmission and then reduced to a
different level of voltage for utilization by using ? . - correct answer-Transformers
An AC voltage that will produce the same amount of power as a like value of DC
voltage is called the ? value. - correct answer-RMS
Another name for the effective value is the ? value. - correct answer-RMS
At how many points along a complete (360°) sine wave will the voltage be equal to
zero? - correct answer-3
At what point is the voltage on a sine wave maximum positive? - correct answer-90°
Each complete revolution (360° travel) of the loop of wire in an AC generator is
called a(n) ? . - correct answer-Cycle
