Engineering Find the voltage across a resistor in a difficult circuit

AI Thread Summary
To find the voltage across resistor R1, the discussion suggests using a voltage divider approach, although there is uncertainty about the current direction from sources I1 and I2. The user is unsure if they need to apply Thevenin's theorem or mesh analysis to determine the current through R1. Another participant recommends using Kirchhoff's Current Law (KCL) equations for analysis. The conversation emphasizes the importance of understanding current flow in complex circuits to solve for voltage accurately.

Homework Statement



Find the voltage across R1 (see attached image).

Note that all values are known.


Homework Equations



Voltager divider might be used. I hope KVL doesn't have to be used here.

The Attempt at a Solution



My problem is that I don't know if the current from I1 is going into the path in which there is R3, because there would be current in the opposite direction (downwards) coming from I2. Do I need to use such anaylses as Thevenin or mess analysis to find the current through R1?

I'd just use KCL equations.
