A three-phase, 460-volt motor draws a current of 52 amperes.
The motor has an efficiency rating of 94% and a power factor of
80%. What is the horsepower?
a. 24.1 hp
b. 41.7 hp
c. 50.0 hp
d. 73.8 hp - ✔✔✔ Correct Answer > b. 41.7 hp
Voltage testers are typically used to:
,Page 2 of 47
a. cut off power to a circuit.
b. distinguish between AC and DC circuits.
c. measure potential differences.
d. verify that the circuit is de-energized. - ✔✔✔ Correct Answer > d
verify that the circuit is de-energized
A 120-volt AC circuit draws a current of 5 amperes. Determine
the power consumption.
a. 60 watts
b. 120 watts
c. 4.8 watts
d. 600 watts - ✔✔✔ Correct Answer > d. 600 watts
Whole circuits manufactured with all components
in place and ready to work are called:
a. semiconductor circuits.
b. microprocessor circuits.
c. rectifier circuits.
d. integrated circuits. - ✔✔✔ Correct Answer > d integrated circuits
What is the psi if the height of a column of
water is 55.4 inches?
,Page 3 of 47
a. 2 psi
b. 4.1 psi
c. 27 psi
d. 55.4 psi - ✔✔✔ Correct Answer > a 2 psi
This is a conversion problem that use formula:
27.7 inches of water = 1 psi Therefore:
54.4 inches x 1 psi / 27.7 inches = 2 psi
How many inches of mercury are required to
obtain a pressure of 4 psi?
a. 4 inches
b. 8.144 inches
c. 54.4 inches
d. 110.8 inches - ✔✔✔ Correct Answer > b 8.144 inches
This is a conversion problem that use formula:
1psi = 2.036 inches of mercury (Hg) at 32° F Therefore:
4 psi x 2.036 inches Hg / 1 psi = 8.144 inches Hg
77°F is equal to how many degrees Celsius?
a. 81°C
b. 60°C
, Page 4 of 47
c. 43°C
d. 25°C - ✔✔✔ Correct Answer > d 25°C
To change from the Fahrenheit scale to Celsius
scale, use formula: °C = 5/9 (°F - 32°) Therefore:
°C = 5/9 (77° - 32°)
°C = 5/9 (45°)
°C = 25
The supply of spare parts, tools, and test instruments should be
monitored by the:
a. supervisory control operation.
b. limited control operation.
c. computer control operation.
d. inventory control operation. - ✔✔✔ Correct Answer > d inventory
control operation
Which of the following is the best choice
of work clothing fabric when working with
electricity?
a. Cotton
b. Nomex
c. Nylon
