Question

Find the equivalent resistance about A,B​

Answer 1

8/3 ohm

this is a wheatstone bridge bcoz ratios of resistances is equal....so u can neglect both the vertical resistances of 4 ohm

u will get three resistances each of 8 ohm connected in parallel combination...

hope this helps...

Answer 2

Check the solution attached.

R eq(AB) = 8/3 ohm.
