EXAM 2025 QUESTIONS AND
ANSWERS
Electromagnetic Interference (5.5.5.5) - ....ANSWER ...-caused when
electromagnetic fields (radio waves) induce high-frequency voltages in a wire or
component. (AC 43.13-1B 11-89)
Grounding (5.5.5.5) - ....ANSWER ...-Establishing a physical wire path that
gives electricity a path to earth/ground.
Bonding (5.5.5.5) - ....ANSWER ...-Connection of non-current carrying
conductive elements ie. enclosures and structures.
Conductor plating (5.5.5.1) - ....ANSWER ...-Copper wire plated with Tin,
Silver, or Nickel. Tin is the most common. wire plating has a slower oxidation rate
than bare copper.

, Voltage drop in wires (5.5.5.1) - ....ANSWER ...-Should not exceed 2% of
the regulated voltage when the generator is carrying rated current or the battery is
being discharged at 5 minute rate.
The allowable voltage drop in a 28 volt continuous circuit is:
a. 1 volt
b. 2 volts
c. 5 volts
d. 4 volts - ....ANSWER ...-a. 1 volt
Voltage rating (5.5.5.1) - ....ANSWER ...-The voltage rating of a cable is the
highest voltage that may be continuously applied to a completed cable construction
in compliance with the relevant cable standard or specification
Shielded wire (5.5.5.1) - ....ANSWER ...-Electrical wire that is enclosed in a
braided metal jacket. Electromagnetic energy radiated from the wire is trapped by
the braid and is carried to ground.
Receiving Inspection (5.4.1.1) - ....ANSWER ...-ensure that incoming parts
are checked against purchase orders, manufacturers specifications, drawings and
dimensions and other available documentation to CONFIRM AUTHENTICITY
of the material. Conformance to applicable technical standards will be verified.
Incoming material must be separated from previously inspected material
