Calculating time constant in RC circuit

Click For Summary
SUMMARY

The time constant (T) in an RC circuit is calculated using the formula T = RC, where R represents resistance and C represents capacitance. The discussion highlights the importance of determining the correct equivalent resistance (Req) when calculating T. A user successfully applied the Thevenin equivalent method to simplify the circuit analysis, confirming its effectiveness in obtaining accurate results.

PREREQUISITES
  • Understanding of RC circuits and their components
  • Familiarity with Thevenin's theorem
  • Basic knowledge of circuit analysis techniques
  • Ability to manipulate algebraic equations
NEXT STEPS
  • Study Thevenin's theorem in detail to apply it effectively in circuit analysis
  • Learn about equivalent resistance calculations in series and parallel circuits
  • Explore practical applications of time constants in electronic circuits
  • Investigate the impact of varying resistance and capacitance on circuit behavior
USEFUL FOR

Electrical engineering students, hobbyists working with circuits, and professionals involved in circuit design and analysis will benefit from this discussion.

I know that T = RC

I've tried different combinations of R (not really sure what Req to take) but none of them worked. Any one can show me the right way ?

Have you tried taking the Thevenin equivalent for point a to b?
 
No I haven't and it was suggested on another forum and it worked. Thank you :)
