2025 QUESTIONS| WITH ALREADY
SOLVED CORRECTLY ANSWERS!! |
ASSURED SUCCESS
A capacitor start motor should be used in what applications? - 🧠 ANSWER
✔✔used for heavy-duty applications requiring high starting torque.
refrigerator compressors, pumps, and conveyors.
You have 120 V super warmer that is not heating. Your meter reads 120 V
from each side of the element to the ground. The voltage across the
element reads 0 V. What is the issue? - 🧠 ANSWER ✔✔Open neutral after
the element
If you check each side of an element terminal to ground and read 120 V
does that mean the element has voltage to it? - 🧠 ANSWER ✔✔No
measure voltage across the load, not from each terminal to ground
A ground fault breaker is considered more reliable than a ground fault
receptacle. T or F? - 🧠 ANSWER ✔✔True

,A thermostat has a differential of 5°F. This means: - 🧠 ANSWER ✔✔the
temperature needs to drop 5 degrees below the set point before the
heating system turns on
Wall receptacles failed due to: - 🧠 ANSWER ✔✔loose wires, overloaded
circuits (tripped breakers), damaged internal components, wear and tear
from frequent use, exposure to moisture, or physical damage which can
lead to poor connections or short circuits.
It is still possible to get shocked by touching the casing of a piece of
equipment if it is properly grounded. T or F? - 🧠 ANSWER ✔✔False
Before working on electrical equipment with the power on: - 🧠 ANSWER
✔✔Proper PPE must be worn, example of this is linesman's gloves
Add 240 V range connected to a 208 V power supply will: - 🧠 ANSWER
✔✔it will likely operate with reduced power and potentially experience
issues like longer cooking times, decreased heating efficiency, and could
potentially be damaged over time
AC power has a negative and a positive line. T or F? - 🧠 ANSWER
✔✔False, it has a hot and a neutral

, Which formula should you use to determine the power consumed by a 15
ohm heater element with 8 A of current flowing through it? - 🧠 ANSWER
✔✔P= I x I x R
A hot line in an AC power supply contains 120 V. T or F? - 🧠 ANSWER
✔✔False, 120 volts is the difference in potential between the hot line and
neutral.
On the ohms law wheel what does P stand for? - 🧠 ANSWER ✔✔Power
Line voltage is the potential difference between: - 🧠 ANSWER ✔✔any two
lines and phases in a three-phase electrical system; essentially, the voltage
measured between two live wires in a power circuit.
Prefix Milli means: - 🧠 ANSWER ✔✔1/1000
The total resistance of a unit but the 230 amp heating elements connected
in a series is: - 🧠 ANSWER ✔✔The total sum of the individual resistances-
RT= R1+R2+R3...
The total resistance in an parallel circuit is called: - 🧠 ANSWER ✔✔1/RT=
1/R1+1/R2...
