Anyone involved in a circuit labora

Anyone involved in a circuit laboratory has spent endless hours helping students debug any or all of the problem classes we have listed. (We note that there may be
other important problems not explicitly listed, e.g. a liquid spilt on the breadboard.) Those faculty and teaching assistants helping students debug circuits depend on experience, debugging tactics and measurements. Notice that none of the techniques used by practitioners is gained by analyzing circuits theoretically or through simulators.
