1. The problem statement, all variables and given/known data Find: a) the equivalent resistor seen by the source; b) value of i0; c) value of v; d) value of v0. http://img823.imageshack.us/img823/4406/dasso.jpg [Broken] 2. Relevant equations Kirchoff's laws and Ohm's laws 3. The attempt at a solution To solve b,c,d I need to get a right which I didn't. I got 6Ω for the equivalent resistor and the right answer is 8Ω. I don't understand why! Isn't the circuit made of those 36Ω and 44Ω in series and the 40Ω,10Ω,30Ω in series and the paralel of those with the rest? I don't get why I got it wrong. Can you people help me?
