✍️ Sample IBEW Questions & Answers

1. What does the word 'NOMINAL' mean as used in electrical specifications?

✓ A named or stated value that may vary slightly in practice

Nominal means 'in name only' — a stated value used for identification that is approximate in practice (e.g., 120V nominal may be 114-126V).

2. A blueprint uses a scale of 1/4 inch = 1 foot. A wall measures 3.5 inches on the blueprint. What is the actual length?

✓ 14 feet

Scale: 1/4 inch = 1 foot, so 1 inch = 4 feet. Actual length = 3.5 × 4 = 14 feet.

3. Use the quadratic formula to solve: x² - 4x - 5 = 0

✓ x = 5 and x = -1

a=1, b=-4, c=-5. Discriminant=16+20=36. x=(4±6)/2. x=5 or x=-1.

4. The sum of the first 5 terms of an arithmetic sequence is 65. If the first term is 5, what is the common difference?

✓ 4

S_n = n/2 × (2a + (n-1)d). 65 = 2.5 × (10 + 4d). 26 = 10 + 4d. 4d = 16. d = 4.

5. Two gears mesh together. Gear A has 12 teeth and Gear B has 36 teeth. If Gear A rotates at 900 RPM, how fast does Gear B rotate?

✓ 300 RPM

Gear ratio = 12/36 = 1/3, so Gear B spins at 900 × (1/3) = 300 RPM.

6. Which sentence uses the word 'circuit' correctly in an electrical context?

✓ The circuit breaker tripped when the load exceeded capacity.

In electrical context, a circuit is a complete path for current flow. Circuit breakers protect electrical circuits.
