Question

8. A wire whose resistance is 40 is cut into
three pieces of equal lengths which are then
joined in parallel. Calculate the resistance
of the combination​

Answer 1

Explanation: length is directly proportional to resistance so when the wire is cut into 3 parts the resistance also becomes 1 by 3 times therefore the resistance of each small part is 40/3

As they are connected in parallel effective resistance =40/3/3=40/9
