Ability to be fused, cost, and the length.
(From P 1-20B)
Now you know better than that. The ability to be fused and the cost are fine, but the length is one of the
factors that determine the resistance of a conductor. How about the melting point? Doesn't that have something to
do with the choice of a conductor? Remember if you wanted a fuse, you would use a material with a low melting
point, and if you were building a light bulb filament, you would use a material with a high melting point. Now,
go back to Page 1-20B and choose the correct answer.
Metallic, nonmetallic, and variable.
Not so. Metallic and nonmetallic are the two types of resistors. The three classifications of resistors,
along with the schematic symbol for each, are listed below.
