SUMMARY

The discussion focuses on solving the equation Q = Q0(e^(-t/RC)) in the context of a homework problem involving resistors R2 and R3. The correct interpretation is that R2 and R3 are in series when the switch opens, leading to a time constant of 0.166 seconds. Participants clarify the confusion regarding the configuration of the resistors, emphasizing the importance of understanding series versus parallel connections in circuit analysis.

PREREQUISITES
  • Understanding of basic circuit theory
  • Familiarity with exponential decay in electrical circuits
  • Knowledge of series and parallel resistor configurations
  • Ability to manipulate and solve equations involving time constants
NEXT STEPS
  • Study the concept of time constants in RC circuits
  • Learn how to analyze series and parallel resistor combinations
  • Explore the implications of exponential decay in electrical systems
  • Practice solving similar problems involving Q = Q0(e^(-t/RC))
USEFUL FOR

Students studying electrical engineering, educators teaching circuit analysis, and anyone looking to deepen their understanding of RC circuits and exponential functions.

2. Homework Equations

Q= Q0(e^(-t/RC))

The Attempt at a Solution



I need help for part C.I am confused as to what value I should put for R.

The answer is supposed to be .166 seconds
 
Physics news on Phys.org
R2 and R3 are in series when the switch opens. Did you get parts a) and b) right?

Find when Q=.25*Q0
 
I was confused because I thought R2 R3 were connected in parallel, but I see why they are in series now. Thanks
