## Homework Statement

Given the circuit in the image (with a current source of 2A and several resistors), what's the voltage in R3?

The answer options are:

1.1V

0.77V

50V

0.55V

## Homework Equations

Ohm's law.

V=RI

## 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.
