100% GUARANTEED PASS!!
<LATEST VERSION>
1. What is the unit of electrical resistance?
A. Volt
B. Ampere
C. Ohm
D. Watt
✅ Correct Answer: C
Rationale: Resistance is measured in ohms (Ω), which indicates opposition to
current flow.
2. If voltage remains constant, increasing resistance will cause current to:
A. Increase
B. Decrease
C. Remain constant
D. Become zero
,✅ Correct Answer: B
Rationale: Ohm’s Law (I = V/R) shows current decreases as resistance increases.
3. A 240 V circuit draws 10 A. What is the power consumed?
A. 240 W
B. 1,200 W
C. 2,400 W
D. 24,000 W
✅ Correct Answer: C
Rationale: Power = Voltage × Current → 240 × 10 = 2,400 W.
4. What happens to total resistance when resistors are connected in parallel?
A. It increases
B. It remains unchanged
C. It decreases
D. It becomes infinite
✅ Correct Answer: C
Rationale: Parallel paths reduce overall resistance by increasing current paths.
5. What is the formula for electrical power?
A. P = I ÷ R
B. P = V × I
C. P = R × I
D. P = V ÷ I
✅ Correct Answer: B
Rationale: Electrical power is calculated using voltage multiplied by current.
,6. What is the maximum allowable voltage for Class 2 circuits?
A. 12 V
B. 24 V
C. 30 V
D. 60 V
✅ Correct Answer: D
Rationale: CEC defines Class 2 circuits as limited to 60 V maximum.
7. The primary purpose of bonding is to:
A. Carry load current
B. Reduce voltage drop
C. Prevent electric shock
D. Improve motor efficiency
✅ Correct Answer: C
Rationale: Bonding ensures exposed metal parts are at ground potential to prevent
shock.
8. What color insulation is required for an equipment bonding conductor?
A. White
B. Black
C. Green or bare
D. Red
✅ Correct Answer: C
Rationale: Green or bare conductors identify bonding/grounding conductors.
, 9. How many current-carrying conductors are allowed in a ¾-inch EMT
before derating applies?
A. 3
B. 6
C. 9
D. 10
✅ Correct Answer: C
Rationale: Derating begins when more than three current-carrying conductors are
installed.
10. GFCI protection is required for receptacles located:
A. In living rooms
B. In kitchens only
C. Outdoors and near water
D. In bedrooms
✅ Correct Answer: C
Rationale: GFCIs protect against ground faults in wet or damp locations.
Section C: Motors & Controls
11. What device protects a motor from overload conditions?
A. Circuit breaker
B. Fuse
C. Overload relay
D. Disconnect switch
✅ Correct Answer: C
Rationale: Overload relays protect motors from overheating due to excess current.
