Question 1 · Electronics Information

The ground wire inside a metal-cased drill has broken, and a worn hot wire touches the inside of the case. What is the main danger?

  • A. The drill will spin in reverse
  • B. The breaker will trip as soon as it is plugged in
  • C. The drill will draw less current than normal
  • D. The case can become live and shock the user
Show the answer
D. The case can become live and shock the user

Without a ground path, current has nowhere safe to go, so the metal case sits at line voltage until a person touches it.

Question 2 · Electronics Information

A household circuit is protected by a 15-amp breaker at 120 volts. What is the most power the circuit can carry before the breaker trips?

  • A. 8 W
  • B. 105 W
  • C. 135 W
  • D. 1,800 W
Show the answer
D. 1,800 W

Power = voltage x current = 120 x 15 = 1,800 W.

Question 3 · Electronics Information

A 12-volt source feeds two parallel branches of 4 Ω and 6 Ω. What is the total current from the source?

  • A. 1.2 A
  • B. 2 A
  • C. 3 A
  • D. 5 A
Show the answer
D. 5 A

Each branch gets 12 V: 12 / 4 = 3 A and 12 / 6 = 2 A, for a total of 5 A.

Question 4 · Electronics Information

A lamp connected to 120 volts draws a current of 0.5 A. How much power does it use?

  • A. 30 W
  • B. 60 W
  • C. 120.5 W
  • D. 240 W
Show the answer
B. 60 W

Power = voltage x current = 120 x 0.5 = 60 W.

Question 5 · Paragraph Comprehension

The swim coach told the team that consistency matters more than any single hard workout. Swimming three times a week, every week, builds more endurance than training for hours one day and then skipping the pool for two weeks. At the end of the season, the swimmers who had kept a steady routine from the first week to the last had improved their race times the most.

As used in the paragraph, "consistency" most nearly means:

  • A. doing something regularly
  • B. working out very hard
  • C. training for long hours
  • D. competing in many swim meets
Show the answer
A. doing something regularly

The coach contrasts swimming three times every week with occasional long sessions, and praises a steady routine.
