5.9 Mesh Currents In applying Kirchhoffs laws, the #of unknown cur- rents is equal to the of branches. Things could be complex. There is a way to reduce the of currents y using mesh currents Example.(see Fig 5-15) R-(l-b)R=0, (l-1b)R-b2B=0. Solution: Ia=3V/5R, I b=V 5R Figure 5-15 Mesh currents in the circuit of Fig 5-11
