Lesson Conductors, Resistors, Insulators and Color Codes
To supply a source of free electrons.
The atomic structure of a material is the greatest factor in determining its resistance.
Resistance would increase.
Its atoms can easily accept and give up electrons.
Yes. Electrons can be made to flow, even in insulators.
Resistance would decrease.
Resistance is the opposition offered to the flow of electrons.
Resistance is the opposition to current flow in a material.
It does not readily accept or give up electrons.
The resistance would stay the same.
Cost, temperature, and melting point.
Melting point, cost, and the ability to be fused.
Fixed, tapped, and metallic.
The five items affecting the choice of a conductor are cost
Resistance is a measure of the amount of current flow in a material.
The length and the cross-sectional area.
The length and the cross-sectional area. - Continued
The specific resistance of a material is the resistance of that material at 30 degrees centigrade.
All the above statements are correct.
The two types of resistors are axial-lead and nonmetallic.
Both of the above.
Complete the statements below by filling in the blanks.
Ability to be fused, cost, and the length.
There are two types and three classifications of resistors.
