For each of the circuits shown in figure 10.6, select a standard tree and state whether the cutset-voltage method or the loop-current method would require fewer Kirchhoff's law equations to be set up. Hence, use the simpler method to solve the circuit completely, i.e., find the voltage and current in each branch of the circuit. (Note: You must find either the set of tree branch voltages or the set of co-tree branch currents first, and then proceed to find all other voltages and currents.)
