    Conditions Zero
AI Thread Summary
Zero initial conditions imply that at time t=0, all currents in inductors and voltages in capacitors are zero, affecting circuit dynamics. This does not mean that voltage sources are replaced by short circuits or current sources by open circuits; those sources remain active. The concept is crucial for analyzing circuit behavior, particularly when determining equivalent Thevenin resistance. Understanding zero initial conditions helps clarify how the circuit responds to power sources without altering the sources themselves. Thus, zero initial conditions focus on the state of reactive components at the initial moment rather than the sources.

Hi all,
a quick question, if we assume zero inital condtions does that mean that we replace each voltage source by a short circuit and a current source with an open circuit??
 
Physics news on Phys.org
? What has "zero initial conditions" mean? Does it mean that we assume at t=0, everything is 0? If so, then what has that got to do with zeroing all the current and voltage sources? That method you described is part of finding equivalent Thevenin resistance. You have to be more explicit.
 
Zero initial conditions means that the currents in all inductors and the voltages in all capacitors are zero at t=0 , so the dynamics of the circuit is a function of the power sources. Of course they cannot be zeroed.
