1. The problem statement, all variables and given/known data The question asks to find the current I going into the 2k resistor path using Y-delta or delta-Y transformations. 2. Relevant equations Resistance in parallel 1 / R = 1 / R1 + 1 / R2 .. Converting Delta to Y, R1 = RaRb / (Ra + Rb + Rc) Current divider formula Ix = (Rt / Rx) * Is 3. The attempt at a solution I converted the delta network of 3 k Ohm resistors into a Y-network of 1k Ohms each using the above equation. (3*3) / (3 + 3 + 3) = 1. Then I got the total resistance of the network as 1.5 k Ohm. Then I used the current divider formula and found I as 2.14 mA. The only problem is I'm not sure if I found the total resistance of the network correctly. It's confusing. Can someone tell me if I did it right?
