The discussion clarifies the concept of short circuits in electrical circuits, specifically addressing the confusion surrounding the resistance of components when short-circuited. When a circuit is short-circuited, the resistance of a resistor (R1) does not become zero if it is not directly in parallel with the short. The current divider principle is applied to find the short-circuit current (Isc) using the formula R1/(R1+r2), emphasizing the importance of understanding series and parallel connections in circuit analysis.
PREREQUISITESElectrical engineering students, circuit designers, and anyone looking to deepen their understanding of circuit analysis and short circuit behavior.
Is R1 in parallel with the short?Frankenstein19 said:
Yes...? If there's a resistor in between does that make them stop being in parallel?phinds said:
I suggest that you go back and study over and over the fundamentals of series and parallel. You HAVE to get that totally straight before trying ANY circuit problems and you have some confusion.Frankenstein19 said:
Yes. If you can't follow a closed path passing through the two components that does not have to pass through any other component along the way, then they are not parallel-connected. Put another way, if two components are parallel-connected, then you can draw a closed path that passes only through that pair of components.Frankenstein19 said:
