ABYC CORROSION COMPREHENSIVE TEST
PAPER WITH COMPLETE SOLUTIONS
●● T/F A galvanic isolator WILL block stray AC.
Answer: False. A galvanic isolator WILL NOT block AC. It will only
blocks stray DC that is moving through the green grounding conductor.
●● T/F An isolation transformer makes a galvanic isolator unnecessary.
Answer: True.
●● An isolation transformer works through electromagnetic _________.
Answer: Induction
●● A reverse polarity indicator is placed between which two wires?
Why?
Answer: White neutral and green grounding.
If the black hot and white neutral are reversed, electricity will flow
through the white neutral illuminating the indicator light and leaving
through the green grounding conductor.
●● Bonding wires shall be at least #__ AWG
Answer: #8 AWG
,●● Electrolytic corrosion is commonly known as:
Answer: Stray-current corrosion
●● Stray-current corrosion is technically called:
Answer: Electrolytic corrosion
●● Matter can exist as a
Answer: Solid, liquid, or gas
●● Matter is made from
Answer: Molecules
●● Molecules are made of
Answer: Atoms
●● Atoms are made of
Answer: protons, neutrons, electrons
●● The atom is electrically
Answer: Neutral. That's because the particles that comprise an atom
balance each other.
, ●● the outer shell of an atom is called the
Answer: Valence shell
●● When the valence shell of an atom is completely filled, the atom is in
its most ______ state.
Answer: Stable.
●● Atoms that have gained or lost an electron are known as
Answer: Ions
●● T/F Ions can have positive or negative charges?
Answer: True.
●● Define Ionization
Answer: The process by which an atom or molecule acquires a charge.
●● What are the two types of chemical bonds?
Answer: Covalent and ionic
●● In covalent bonds, atoms form chemical bonds by _______
electrons.
Answer: Sharing.
