Question

Problem: Find the currents flowing in the circuit in the figure below. (Assume the resistances are

R₁ = 12 Ω, R₂ = 6 Ω, R₃ = 15 Ω, R₄ = 8 Ω, r₁ = 0.25 Ω, r₂ = 0.75 Ω, r₃ = 0.25 Ω and r₄ = 0.75 Ω. E1= 18V, E2= 3.0V, E3= 12V, E4=24V.

These are the equations I got:

I1 = I2 + I3

21= 18.25*I1 + 20.25*I3

15= 20.25*I3 - 6.75*I2

Am I doing this right? Images for the figure can be found on similar posted problems on Chegg. I can't seem to upload my own picture.

Answer 1

These three equation are correct for this circuit.
