AI Thread Summary
The discussion focuses on solving for the mesh current iΔ using the equations derived from the circuit analysis. Two key equations are established: 5mA + 15.4*i1 - 5.4*i2 = 0 and 9.1*i2 + 5.42*i1 - 150iΔ = 0. The user expresses confusion about how to proceed with two equations and three unknowns, indicating a need for clarification on the relationships between the currents. Additionally, there is a request for guidance on determining the polarity of the individual currents based on a clockwise reference. A circuit diagram is also requested to aid in visualizing the problem.

Homework Statement


Use mesh current to solver for iΔ

Homework Equations


v1+v2+... vn=0
i=v/R

The Attempt at a Solution


5mA+15.4*i1-5.4i2=0
9.1*i2+5.42*i1-150iΔ=0

Now I have two equations and three unknowns and I'm unsure how I should proceed. Also, how do I tell what polarity the individual currents are, assuming my reference is a clockwise voltage?
