1) Alternating Current (AC) always flows one True. AC always flows one way
way then the other? then the other.
2) The frequency of AC is measured in? Measured in hertz Hz
3) What refers to a voltage that can convey Electrical Signal
information?
4) What refers to the maximum voltage that Amplitude
can be reached by a signal?
5) Electricity may flow only when? There has to be a for it to return
making a complete circuit
6) What is the return path for electrical power Neutral
to flow back to the service panel?
7) The live wire is always ungrounded? True. They are very hot caring
electrical power
8) A ground electrode conductor originates at True
, the neutral or equipment ground bus of the
service panel?
9) A ground electrode should not make contact False
with the earth?
10) What is the difference between watts and Watts are the measure of power.
voltage? Voltage is the measure of potential
energy.
11) You should size conductors no less ______ 125% / 100%
of the continuous loads plus _________ of
the non-continuous loads,.
12) Conductor sizes are often expressed using? American Wire Gage (AWG)
13) What refers to the allowable current- Ampacity
carrying capacity of a conductor?
14) The insulation type determines the areas Yes, the type of insulation on an
where electrical wires can and cannot used? 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.
15) RHH wires use rubber insulation that is Suitable for dry locations
high heat resistant and is good in?
, 16) RHW-2 wires use the rubber insulation but Yes, RHW-2 wires utilize rubber
are suitable for wet locations? 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.
17) What cables can be used inside wall, ceiling Non-metallic (NM)
or under the floor.
18) What cables are most appropriate for damp For damp locations, cables like
areas? THW (Thermoplastic, Heat and
Water Resistant), THWN
(Thermoplastic, Heat and Water
Resistant), THWN-2
(Thermoplastic, Heat and Water
Resistant, with higher temperature
rating), RHW (Rubber, Heat and
Water Resistant), and RHW-2
(Rubber, Heat and Water Resistant,
with higher temperature rating) are
suitable. These cables are designed
to withstand moisture and are
