Question

The figure below shows five resistors and two batteries connected in a circuit. What are the currents I₁, I₂, and I₃? (Consider the following values:

R₁ = 1.20 Ω,

R₂ = 2.06 Ω,

R₃ = 3.20 Ω,

R₄ = 4.06 Ω,

R₅ = 6.20 Ω.

Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign. Indicate the direction with the sign of your answer.)
