Prob 8-31 Fig 8-86 Write the mesh equations and solve for the loop currents. At I1: -I1R1-2 – I1R2 +I2R2 -4 – I1R4 + I3R4 = 0 => -I1*3 –2 – I1*1 +I2*1 -4 –I1*6 + I3*6 =0 -I1 (3+1+6) +I2*1 + I3*6 -2-4=0 => -I1*10 +I2 +6*I3= 6 => I1(-10) + I2(1) + I3(6) = 6 At I2: 4 – I2R2 + I1R2 + 6 – I2*R3 – I2*R5 +I3*R5 = 0 => 4 – I2*1 + I1*1 + 6 – I2*4 –
