Question 1 of 10
What does AWG stand for?
AWG stands for American Wire Gauge, a standardized wire sizing system.
Question 2 of 10
As the AWG number increases, the wire diameter...
Higher AWG numbers indicate smaller wire diameters.
Question 3 of 10
Which of the following is NOT a unit used to express wire cross-sectional area?
Volts is a unit of electric potential, not area. mm², in², and kcmil are all used to represent the cross-sectional area of a wire.
Question 4 of 10
What is another term for 'thousands of circular mils'?
MCM, or thousands of circular mils, is used for large diameter wires.
Question 5 of 10
The resistance of a wire is dependent on which of the following?
All of these factors affect wire resistance.
Question 6 of 10
At what temperature are the resistance calculations typically referenced?
The reference temperature is 20°C (or 68°F).
Question 7 of 10
What unit is used for resistivity (?)?
Resistivity is measured in Ohm-meters (?·m).
Question 8 of 10
Which of the following is true regarding the relationship between AWG size and current carrying capacity?
Smaller AWG sizes (larger diameter wires) can carry more current without overheating.
Question 9 of 10
What is the approximate equivalent of 1 kcmil in mm²?
1 kcmil is approximately equal to 0.5067 mm².
Question 10 of 10
Which material generally has the lowest resistivity, making it ideal for wire?
Copper has a low resistivity, which means it resists the flow of electricity less, and is therefore preferred in electrical wiring.
