Question

Resistance of conductor :
(a) increases with the increase in its area
(b) increases with th
e increase in its length
(c) decreases with the decrease in its length
(d) does not depend on change of its length and area.
llowing door not renresent electrical no​

Answer 1

Answer:

c. decreases with the decrease in its length.

Answer 2

Answer:

b)increases with increase in its length and

c)Decreases with decrease in its length

Step-by-step explanation:

Resistance of a wire is given by the formula

R=Ro l/A

Where Ro stands for specific resistance

l stands for length

and A stands for area of cross section.

for a given material and temperature, Ro is always constant

this implies that R is directly proportional to l(if Area is same) and inversely proportional to A (If length is same)

hence, option b and c are the answers.
