Select all that apply. which of the following factors influence the electrical resistance of a circuit?
a) conductivity of the material
b) length of conducting wires
c) diameter of conducting wires
d) type of battery installed

explanation:

resistance is the opposition to the flow of current. the relation between electrical resistance, conductivity, length and area is as follows.

where,       r = resistance

                = resistivity

                  l = length

                a = area

also, area = . therefore, when there is change in length, area, or resistivity then there will be change in resistance also.

the ability of electric current to flow through the wire or material is known as conductivity. symbol for conductivity is .

thus, conductivity is also related to resistance.

hence, we can conclude that the following factors influence the electrical resistance of a circuit.
