Solve the circuits diagrammed in the attached sheets. Try to solve each
circuit by both loop currents and nodal voltages, and compare the two
solutions. Circuit simplification can sometimes reduce the solution effort
considerably.
In the diagrams, resistances ere given in ohms. Answers are listed below,
giving selected voltages and currents.
