• Manage time effectively
• No negative marking unless specified
1. A technician measures 480 VAC RMS on a waveform. What is the approximate peak voltage of
this waveform?
A) 480 V
B) 339 V
C) 679 V
D) 960 V
Answer: C
*Peak voltage = RMS × 1.414; 480 × 1.414 = 678.7 V.*
2. You are working on a brake coil with an inductance of 4 henries in a 60 Hz circuit. What is the
inductive reactance?
A) 240 Ω
B) 1507 Ω
C) 15 Ω
D) 377 Ω
, Page 3 of 115
Answer: B
*XL = 2πfL = 2 × 3.14 × 60 × 4 = 1507 Ω.*
3. A relay contact fails due to excessive arcing. What is the most effective method to reduce this
arcing?
A) Increase coil voltage
B) Install a noise suppression capacitor or MOV across the contacts
C) Reduce load current
D) Use a smaller relay
Answer: B
Snubber circuits (capacitors or MOVs) absorb arc energy, preventing contact welding and pitting.
4. When a cam or vane is moved close to a magnetic levelling switch, what occurs?
A) The relay energizes
B) The switch changes its state
C) The LED turns off
D) The capacitor discharges
Answer: B
, Page 4 of 115
Magnetic levelling switches use a magnetically actuated reed that changes state when a ferrous
vane approaches.
5. In a purely inductive AC circuit, by how many degrees does the current lag the voltage?
A) 0°
B) 45°
C) 90°
D) 180°
Answer: C
Inductors oppose current changes, causing current to reach its peak one-quarter cycle after
voltage.
6. A capacitor has a time constant of 0.3 seconds with a 150 kΩ resistor. What is the
capacitance?
A) 2 μF
B) 5 μF
C) 10 μF
D) 0.5 μF
