If the terminals of an ideal voltage source are connected through a conductor, then there will be a theoretical contradiction and a probable explosion. That’s why it is common advice NOT to short the terminals of a battery. Dependent Voltage Source The voltage across a dependent voltage source is dependent on (proportional to) the voltage or current ( x ) in another element in the circuit. Depending on the control element (x), it can be voltage‐controlled voltage source or a current‐controlled voltage source. vs Kx Fig. Dependent Voltage source 14 EE1002 Introduction to Circuits and Systems Electric Power and Sign Convention Because current is r...
