If n equal resistance are first connected in series then find the equivalent resistance

Explanation

To find the magnitude of the displacement, measure the straight distance between Bhubaneshwar and Delhi on the map of India. Then convert the straight distance into km as per given scale in the map.
`to` From the map this straight distance (i.e., displacement) is approximately 1270 km (For displacement the aerial distance between the two cities can also be considered.)
