Question 1

An electrical project is estimated to take 120 hours. After 3 weeks of 35 hours each, what percentage of the project is complete?

Accepted Answer

87.5%

Answer

3 × 35 = 105 hours; 105 ÷ 120 = 0.875 = 87.5%.

Accepted Answer

86.5 ft

Answer

22.5 + 18.75 + 31.25 + 14 = 86.5 ft.

Question 3

If wire costs $2.35 per foot, how much wire can be purchased for $200, and approximately how many full feet is that?

Accepted Answer

85 feet

Answer

$200 ÷ $2.35 ≈ 85.1, so 85 full feet.

A voltage drop calculation shows a 3.5% drop on a 240V circuit. What is the voltage at the load end?

Accepted Answer

231.6 V

Answer

240 × 0.035 = 8.4 V drop; 240 − 8.4 = 231.6 V.

Question 5

A work order lists labor at $85/hr for 14 hours and materials at $620. What is the total job cost?
