Engineering Basic Engineering Circuit Problem 2

AI Thread Summary
The circuit problem requires finding the current I1, with the equation I1 + 4 mA = 2 mA leading to I1 = -2 mA. However, the discussion highlights that there are two unknowns in the circuit, suggesting the need for a second equation to solve for both I1 and the current through the resistor between the 2 mA and 12 mA legs. This indicates that additional information or equations may be necessary for a complete solution. The complexity of the circuit is acknowledged, emphasizing the importance of considering all components and currents involved. A thorough analysis is essential for accurately determining I1.

This problem looks to have 2 unknowns. You aren't given the current flowing through the resistor on the left between the 2mA and 12mA legs. I would think you would need to write 2 equations to solve for I1 and that unknown current, but I could be wrong.
