SUMMARY

The discussion centers on determining whether resistances in a circuit are arranged in series or parallel. The user identifies that the ends of the resistances are not directly connected, indicating a parallel configuration is unlikely. The conversation highlights the need to replace reactive elements, such as capacitors and inductors, with their equivalent resistances at time t = 0+. The resistors in question are specified as 5 ohms and 20 ohms, with the user questioning the equality of current through them.

PREREQUISITES
  • Understanding of circuit theory, specifically series and parallel resistor configurations.
  • Knowledge of reactive components, including capacitors and inductors.
  • Familiarity with equivalent resistance calculations.
  • Basic principles of electrical current and its behavior in circuits.
NEXT STEPS
  • Study the principles of series and parallel circuits in detail.
  • Learn how to calculate equivalent resistance for circuits with reactive components.
  • Explore the behavior of capacitors and inductors at t = 0+ in transient analysis.
  • Investigate current division in parallel circuits and its implications.
USEFUL FOR

Electrical engineering students, circuit designers, and anyone involved in analyzing or designing electrical circuits.

Homework Statement


I just want to know if the resistances are in parallel or series.


Homework Equations





The Attempt at a Solution



The ends of the resistances are not connected to each other ( there are other circuit elements in between). So, that's why I don't think they are in parallel. But then again the current through R1 and R2 won't be equal would they? So what should Requivalent be?

The problem is asking about conditions at time t = 0+. Your first order of business should be to replace the reactive elements (capacitor, inductor) with their equivalent resistances at that instant. Then look at the circuit again.
 
I don't see any R1 and/or R2, but if you are talking about the 5ohm and 20ohm resistors, I can't imagine why you would think the current through them would be the same. Am I perhaps misunderstanding what you are saying?
