Question

What is meant by resistance of a conductor? Name and define its SI unit. List the factors on which the resistance of a conductor depends. How is the resistance of a wire affected if: (i) its length is doubled, (ii) its radius is doubled?

Answer 1

Answer:

resistance of a conductor is defined as the amount of current passing through area of cross section in unit time

Explanation:

R=V/I=volt/ampere =ohm

resistance depends upon length of conductor

its area

and material used

if length is double R becomes 4 times and R decreases if radius increase
