EEI TECH Test — Questions and Answers

Question 1: What is the purpose of a Job Hazard Analysis (JHA) before starting work?

Identify potential hazards and plan controls before starting the task (Correct answer)
Document completed work
Assign overtime pay

Correct answer: Identify potential hazards and plan controls before starting the task

A JHA systematically identifies hazards associated with each step of a job and determines controls before work begins.

Question 2: An instruction reads: 'Do not energize until all covers are secured.' A technician is ready to apply power but one cover is loose. What should the technician do?

Skip the cover and proceed
Energize carefully
Secure the loose cover first (Correct answer)

Car
There is no difference. (Correct answer)
Ball

Correct answer: There is no difference.

According to Galileo's law of falling bodies, in the absence of air resistance, all objects fall at the same rate regardless of their mass. Both a car and a bowling ball experience the same acceleration due to gravity (approximately 9.8 m/s²), meaning they would hit the ground simultaneously. While air resistance exists, for these objects, its effect is generally not significant enough to cause one to hit substantially earlier than the other in this scenario.

Only online forums can provide practice tests.

Correct answer: EEI's website

The most reliable and official source for study guides for EEI exams, including the TECH test, is directly from EEI's website. This ensures you receive accurate, up-to-date, and relevant preparation materials directly from the test administrator, unlike potentially outdated or unofficial resources found on online forums or in libraries.

Question 56: A container of water has a small hole near the bottom and another near the top. Water sprays out:

Faster from the bottom hole (Correct answer)
At the same speed
Faster from the top hole
Only from the top hole

Question 66: Which switch should be turned off to turn on the light?

Switch A
Switch B
Switch C (Correct answer)

Correct answer: Switch C

The light bulb is connected in parallel with Switch C. When Switch C is closed (on), it creates a short circuit, diverting current away from the light bulb and preventing it from lighting up. To turn the light on, current must flow through the bulb, so Switch C must be open (off) to force the current through the bulb. Switches A and B must be closed (on) for the circuit to be complete.

Reduce load and continue
Reset the voltmeter
Continue monitoring
Shut down and notify control center (Correct answer)

Correct answer: Shut down and notify control center

132V exceeds 130V, so the procedure requires an immediate shutdown and notification.

10
12
14
16 (Correct answer)

Correct answer: 16

In one of the specific sections of the EEI TECH exam, candidates are expected to answer 16 questions within an allotted 15 minutes. This tight time constraint emphasizes the importance of quick problem-solving and efficient test-taking strategies for that particular module.

Question 82: Henry is shorter than Luis. Henry is taller than Cris but not as tall as Luis. Kevin is taller than Cris but not as tall as Henry. Who is the tallest?

Luis (Correct answer)
Kevin
Henry
Cris

Correct answer: Luis

To determine the tallest person, we establish a hierarchy based on the given comparisons. 'Henry is shorter than Luis' means Luis > Henry. 'Henry is taller than Cris' means Henry > Cris. 'Kevin is taller than Cris but not as tall as Henry' means Henry > Kevin > Cris. Combining these, the order from tallest to shortest is Luis > Henry > Kevin > Cris. Therefore, Luis is the tallest. The other options are incorrect because they are all shorter than Luis according to the established order.

Question 90: What is the purpose of a neutral conductor in a standard 120V circuit?

Carry voltage to the load
Provide a return path for current to the source (Correct answer)

Correct answer: Provide a return path for current to the source

The neutral conductor completes the circuit by carrying return current back to the power source.

Question 91: If the second of the month is a Tuesday, what day is it on the 21st of that month?

Tuesday
Sunday (Correct answer)
Saturday
Monday

Correct answer: Sunday

To find the day of the week on the 21st, calculate the number of days between the 2nd and the 21st, which is 21 - 2 = 19 days. Since a week has 7 days, divide 19 by 7 to find the remainder: 19 = 2 weeks and 5 days. Therefore, starting from Tuesday, count forward 5 days (Wednesday, Thursday, Friday, Saturday, Sunday) to arrive at Sunday. Options A, B, and D are incorrect as they do not account for the correct number of days or the cyclical nature of the week.
