ABSTRACT
In the first chapter it was mentioned that the delta current pulse i(t) = ev;.8(t) transporting in zero time an amount of charge Q = ev;., is an unbounded current. The concepts bounded and unbounded currents come from some considerations in network theory related to circuits including capacitors and switches (or, more general, stepping voltages). As such they are closely related to intriguing networks, such as the switched capacitor network of figure Fig. 7.1 that seem to violate energy conservation. They are also related to the description of energy in networks that have reduction in "free-energy" and thus to nanoelectronics.
