Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Which factors affect resistance (select all that apply)?

A	the type of material
B	temperature
C	width or length of a conductor
D	mass of an object

Explanation:

Detailed explanation-1: -The four factors which affect the resistance of a conductor are Resistivity, Temperature, Length, and Area of Cross Section.

Detailed explanation-2: -Length of the conductor-Resistance is directly proportional to the length of the conductor. Area of the cross-section of the conductor-Resistance is inversely proportional to the cross section area of the conductor. Material of the conductor-Resistance depends on the material of conductor.

Detailed explanation-3: -The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. Resistance also depends on the material of the conductor. See resistivity.

Detailed explanation-4: -The type of material of which the resistor is made. The length of the resistor. The thickness of the resistor. The temperature of the conductor.
