Interconnectionsamong components (how wires are connected to move elec-

tricity from one component to another) in a circuit are made with wires or bits

of copper placed on a breadboard. A schematic won’t usually specify which

kind of connection you are using, only that a connection exists. Figure 4-3

shows a few methods of representing interconnections.
