ABYC Corrosion Questions and
Answers Graded A+


GFCI stands for... - answer Ground Fault Circuit Interrupter

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: - answerStray-current corrosion

Stray-current corrosion is technically called: - answerElectrolytic corrosion

Matter can exist as a - answerSolid, liquid, or gas

Matter is made from - answerMolecules

Molecules are made of - answerAtoms

Atoms are made of - answerprotons, neutrons, electrons

In covalent bonds, atoms form chemical bonds by _______ electrons. - answerSharing.

E.g. water, H2O

In ionic bonds, atoms form chemical bonds by _______ electrons. - answerGiving up or

The atom giving an electron become a positive ion. The atom gaining an electron
becomes a negative ion. Oppositely charged bodies are attracted to each other,
bonding them together.

E.g. Sodium Chloride, NaCl, table salt.

T/F Atoms in the valence shell are involved in the corrosion process? - answerTrue

What is disassociation with regard to electrolyte? - answerWhen an ionic substance
(like sodium chloride, table salt) is immersed in water it disassociates, or separates, into
positive and negative ions.

__________ are electrical conductors in which current is carried by ions rather than by
free electrons. - answerElectrolytes

The three categories of corrosion are: - answerElectrochemical, galvanic, and
electrolytic

Single-metal corrosion is technically referred to as - answerElectrochemical corrosion

Electrochemical corrosion is commonly known as - answerSingle-metal corrosion

Galvanic corrosion is sometimes referred to as - answerTwo-metal corrosion or bi-
metallic corrosion

Corrosion is often improperly called - answerElectrolysis.
