EEE 360 EXAM 1 FINAL PAPER TEST
BANK EXAM Q&A 2026 100% CORRECT.
◉ If the power is negative, the element is absorbing or supplying
power. Answer: supplying, like a generator.
◉ The RMS value of v(t) = Vmaxcos(wt + theta) is given by:
Answer: Vmax / 2^0.5
◉ For balanced wye-delta loads, Z delta = ? Answer: Z delta = 3Zy
◉ For delta transformers, Vphase = ? Answer: V line to line. There is
no neutral
◉ In wye circuits, Phase = ? Answer: V line to neutral voltage
◉ Step-down transformers Answer: Wye-delta transformers are
frequently used as this.
◉ current magnitude Answer: I_M = rad(2)I_rms
◉ Complex Power (VA) Answer: S = V_rms x I*_rms;
S = P + jQ
, the rating of power equipment is described by the apparent power, S,
also measured in volt-amperes
P = real power
Q = reactive power
◉ In this circuit, the current lags the applied voltage Answer:
inductive
◉ In this circuit, the current leads the applied voltage Answer:
capacitive
◉ Resistor real power equation Answer: S_R = V_R x I*
◉ Capacitive reactive power [negative] equation Answer: S_C =
V_C x I*
◉ Voltage source complex power equation Answer: S_S = V_S x I*
◉ Voltage regulation Answer: The difference between the
magnitudes of the voltage at the load terminals for the no-load (V_no-
load) and (full) load conditions divided by the load voltage (V_load)
magnitude
◉ Voltage regulation generalizations Answer: Typically, the voltage
regulation should be less than 10%.
