Question

For the circuit shown in Figure Pl8.30, use Kirchhoff's rules to obtain equations for (a) the upper loop, (b) the lower loop and (c) the node on the left side. In each case suppress units for clarity and simplify, combining like
terms. (d) Solve the node equation for l36. (e) Using the equation found in (d), eliminate l36 from the equation found in part (b). (f) Solve the equations found in part (a) and pan (e) simultaneously for the two unknowns for l18 and  l12, respectively. (g) Substitute the answers found in part (f) into the node equation found in part (d ), solving forl36 . (h) What is the significance of the negative answer for l12?
