1. The problem statement, all variables and given/known data Twelve resistors of equal resistance are connected so as to form a cube ABCDEFGH shown. Equivalent resistance between points A and G is 5/3 ohm. If a battery of voltage 100 V is connected across the points A and G, find the current (in ampere) flowing through the resistor CD. 2. Relevant equations V=IR 1/Rparallel = 1/R1 + 1/R2 + ... Rseries = R1 + R2 + ... 3. The attempt at a solution V=IR So 100=i*5/3 ( between A and G ) So current between A and G is i=60 . But what now ? How to calculate current between C and D ?
