The discussion revolves around the analysis of a first-order R-L circuit, specifically focusing on the behavior of current at the moment a switch opens in the circuit. Participants are exploring the relevance of certain equations and initial conditions necessary for solving the circuit problem.
Participants express uncertainty about the relevance of certain equations and the initial conditions needed for the analysis. There is no clear consensus on the correctness of the initial conditions or the equations being discussed.
Participants have indicated confusion regarding the initial conditions and the application of certain equations, which may depend on specific definitions or assumptions not fully articulated in the discussion.
Students and educators involved in electrical engineering or circuit analysis, particularly those studying R-L circuits and initial condition behaviors.
It isn't exactly a related equation but I couldn't leave it empty so I put it there, i have attempted a solution on my own, but my question is just if the current at the instant before the switch opens=the current at the instant right after the switch opens. I just want to know if that's correct or not because it's relevant if I want to continue solving the rest of the question with my solution.BvU said:
Okay, my professor's lecture was very confusing and didn't properly explain initial conditions, but now I used outside sources to study and my confusion about the question is cleared so I'll delete this in a bit.BvU said:
You have picked up the essential part of this exercise: the inductance will behave in such a way that a change in current is counter-acted, according to the relationship $$V = L{di\over dt}$$so: bravo, well done !Xiao Xiao said:
