P 4.6-10 The mesh currents in the circuit shown in Figure P 4.6-10 are

i₁ = –2.2213 A, i₂ = 0.7787 A, and i₃ = 0.0770 A

(a) Determine the values of the resistances R₁ and R₃.

(b) Determine the value of the power supplied by the current source.

Figure P 4.6-10

We have one Supermesh between i₁ and i₂. The two equations are:

and

Remaining i₃ mesh equation is

Use second equation to solve for R₁

Using the third equation we can solve for R₃

To get power of current source we can do a voltage walk to determine v_s across I_s

Left loop

Check with right loop
