9. Q9: How many MVARs does a 230 kV, 50 MVAR capacitor bank provide when
the voltage is 207 kV?
A) 50 MVARs
B) 45 MVARs
C) 40 MVARs
D) 35 MVARs: C) 40 MVARs
10. Ql0: Voltage response to power flow is a study that is represented by which
of the following?

B) P-V Curve
C) Ferranti Curve

11. Q11: Two adjacent lines exist in a Balancing Area that are the same length
and have the same ratings. One line is overhead and the other is underground.
How do these two lines respond as load picks up through the day?
A) The overhead line will carry more of the load increase
B) The underground line will carry more of the load increase
C) The load increase will be distributed evenly over the two lines
D) The line with the higher impedance will carry more of the load: B) The
underground line will carry more of the load increase Feedback: EPRI Tutorial: Due
to its higher capacitive property, the underground cable will have lower impedance
and therefore carry more of the increase.

sion lines where Line A is 150 miles long and Line B is 15 miles long. Which
statement is true if both lines are lightly loaded?
A) A produces the same reactive power as B
