... Figure 5–3b shows how to assemble axial-lead resistors on a lab prototype board to form a parallel circuit. Just as in a circuit with one resistance, any branch that has less R allows more I. If R1 and R2 were equal, however, the two branch currents would have the same value. For instance, in Fig. 5 ...
