Question

the statement is not correct when relates to resistance of a conductor

a) resistance increases when length increases

b) resistance increases when cross sectional area decreases

c) resistance increases when cross sectional area increases

d)resistance increases when temperature increases ​

Answer 1

Answer:

Now you can find out

Explanation:

Since the resistance of some conductor, such as a piece of wire, depends on collisions within the wire itself, the resistance depends on temperature. With increasing temperature, the resistance of the wire increases as collisions within the wire increase and "slow" the flow of current.

Answer 2

b)resistance increases when cross sectional area decreases
