Alternating Current (AC) always flows one way then the other? - 🧠ANSWER
✔✔True. AC always flows one way then the other.
The frequency of AC is measured in? - 🧠ANSWER ✔✔Measured in hertz
Hz
What refers to a voltage that can convey information? - 🧠ANSWER
✔✔Electrical Signal
What refers to the maximum voltage that can be reached by a signal? -
🧠ANSWER ✔✔Amplitude
,Electricity may flow only when? - 🧠ANSWER ✔✔There has to be a for it to
return making a complete circuit
What is the return path for electrical power to flow back to the service
panel? - 🧠ANSWER ✔✔Neutral
The live wire is always ungrounded? - 🧠ANSWER ✔✔True. They are very
hot caring electrical power
A ground electrode conductor originates at the neutral or equipment ground
bus of the service panel? - 🧠ANSWER ✔✔True
A ground electrode should not make contact with the earth? - 🧠ANSWER
✔✔False
What is the difference between watts and voltage? - 🧠ANSWER ✔✔Watts
are the measure of power. Voltage is the measure of potential energy.
You should size conductors no less ______ of the continuous loads plus
_________ of the non-continuous loads,. - 🧠ANSWER ✔✔125% / 100%
Conductor sizes are often expressed using? - 🧠ANSWER ✔✔American
Wire Gage (AWG)
, What refers to the allowable current-carrying capacity of a conductor? -
🧠ANSWER ✔✔Ampacity
The insulation type determines the areas where electrical wires can and
cannot used? - 🧠ANSWER ✔✔Yes, the type of insulation on an electrical
wire does determine the environments where it can be safely used.
Different insulation materials are designed to withstand different conditions,
such as moisture, temperature, chemicals, and UV exposure.
RHH wires use rubber insulation that is high heat resistant and is good in? -
🧠ANSWER ✔✔Suitable for dry locations
RHW-2 wires use the rubber insulation but are suitable for wet locations? -
🧠ANSWER ✔✔Yes, RHW-2 wires utilize rubber insulation and are
specifically designed for use in wet locations. The "W" in RHW-2 indicates
moisture resistance, making it suitable for environments where dampness
or water exposure is possible.
