ETCP ENTERTAINMENT ELECTRICIAN
EXAM QUESTIONS AND VERIFIED
ANSWER; 100% CORRECT; 2026 UPDATE




0° Phase Angle - correct answer- purely resistive, no
reactance


90° Phase Angle - correct answer- purely reactive, no
resistance (not possible)


Apparent Power - correct answer- (kVA) vector sum of real
and reactive power


Capacative Load - correct answer- current leads voltage


Causes of low PF - correct answer- a load with high
reactance


Consequences of low PF - correct answer- inefficiency, loss
of energy through heat, larger gauge conductors required

, Delta - Phase Current to Line Current - correct answer-
Phase Amps * √3 = Line Amps


Delta - Phase Voltage to Line Voltage - correct answer-
Phase Voltage = Line Voltage on a delta transformer


How is a low PF corrected? - correct answer- adding the
opposite type of reactance


Inductive Load - correct answer- current lags voltage


Instantaneous Power - correct answer- power at any
instant in time


kVA = - correct answer- kVA (apparent power) = V (voltage)
* I (amperage) * 1000


LED fixtures without PF correction tend to have a PF of? -
correct answer- 0.5


Low or High PF? - correct answer- you want a high power
factor, low will cause more current
