In the arrangement, 11 wires each of resistance `5Omega` are used as sides of cube. A potential difference of 70 V is maintained between corners A and B of cube.
Current flowing in wire Ef is

A

4A

B

2A

C

5A

D

10A

Text Solution

Verified by Experts

The correct Answer is:
C
The equivalent circuit diagram is as shwn.

`R_(AB) = (7r)/(5) or I = (5V)/(7r) = (5xx70)/(7xx5) = 10A`
