In the adjoining network of resistors, each is of resistance r ohm, the equivalent resistance between points A and B is–

A

`(hati+sqrt3hatj)m//s`

B

`(hati-sqrt3hatj)m//s`

C

`(2hat(i) + sqrt3hat(j)) m//s`

D

`(2hati+2hatj)m//s`

Text Solution

Verified by Experts

The correct Answer is:
(A)

`v_(A) = 4 sin 30^(@)[cos60hat(i) + sin 60hat(j)] = hat(i) + sqrt3hat(j)`
