4. Kirchhoff's voltage law says that the sum of the voltage drops around any closed path in the network in a given direction is zero. When this principle is applied to the circuit shown in Figure 3.5, we obtain the following linear system of equations:
(R1+R3+R4)I1+ R3I2+ R4I3=E1
(1) R311 + (R2 + R3 + R5)12 ? R513 =
R411 ? R512 + (R4 + R5 + R6)13 = 0.
Use Program 3.3 to solve for the current 11, '2, and 13 if
(b) I?i = 1, R, = 0.75, R3 = 1, R4 = 2, R5 = 1, R6 = 4, and E1 = 12,
E2 = 21.5
(c) R1 = 1, R2 = 2, I?3 = 4. R4 3, R = 1, R6 = 5, and E1 = 41, E2 = 38
