1. The problem statement, all variables and given/known data Given the circuit in the image (with a current source of 2A and several resistors), what's the voltage in R3? http://postimg.org/image/yl6czh9u7/ The answer options are: 1.1V 0.77V 50V 0.55V 2. Relevant equations Ohm's law. V=RI 3. The attempt at a solution I tried to simplify the circuit. The circuit equivalent resistor I found was (((((R6 || R7) + R5) || R8) + R4) || R3) + R1 + R2 From my calculation the equivalent resistor is 32,5Ω And the voltage of the circuit is 65V If the voltage in R1 is 10V (2A x 5Ω) and in R2 is 30V (2A x 15Ω) in R3 it should be something like 25V... but that is none of the options! Thanks for any help.
