Example network 1 below illustrates the simplification process in three steps.
Distances are drawn in relative proportion. The numbers represent +5V application
currents, with 5x25 indicating 5 nodes of 25mA each at the same location. Use the
equivalent power network from Step Three when applying the extended power
performance specification.
