To find the currents. one uses these two laws to write down equations and tries to solve them Example. (See Fig 5-11)three unknowns I1, 12, I3 Writing down three equations 1=12+l3,(atA) V-I1R-I3R=O,(left mesh) I3R-I2R-I2R=0(right mesh Solution: I1=5K, I2=R, I3=2k R 1, R R Figure 5-11 One can calculate I1, I2, I3, given R and v
