How to Find Equivalent Capacitance?

Click For Summary
SUMMARY

The discussion focuses on calculating the equivalent capacitance of a circuit involving capacitors in both series and parallel configurations. The user initially calculated the equivalent capacitance for two sets of capacitors in series, resulting in values of 2/3 µF and 15/8 µF, respectively. The user expressed confusion regarding the correct order of operations for combining these capacitors, particularly when considering parallel connections. The recommendation to explore delta-wye transformations was provided as a potential solution to clarify the order of addition.

PREREQUISITES
  • Understanding of series and parallel capacitor configurations
  • Familiarity with the formula for equivalent capacitance in series: 1/C = 1/C1 + 1/C2
  • Knowledge of the formula for equivalent capacitance in parallel: C = C1 + C2
  • Basic grasp of delta-wye transformations in circuit analysis
NEXT STEPS
  • Study the principles of delta-wye transformations in electrical circuits
  • Practice calculating equivalent capacitance with complex circuits
  • Explore advanced circuit analysis techniques, such as mesh and nodal analysis
  • Review examples of circuits with mixed series and parallel capacitors
USEFUL FOR

Students studying electrical engineering, circuit designers, and anyone involved in analyzing or designing capacitor networks in electronic circuits.

Homework Statement



Hi, i was working on finding the equivalent capacitance, but I'm not sure if I'm doing it right
This is the figure : http://i8.photobucket.com/albums/a8/ryu0919/physicsproblem2.jpg?

Find the equivalent capacitance?

The Attempt at a Solution



I thought of adding the top in series, and i got 1/C = 1/2 + 1/1 = 3/2 so C = 2/3
on the bottom, i added them in series too and i got 1/C = 1/3 + 1/5 = 8/15 so C = 15/8
then i thought i could add all of them in parallel and i added 2/3+15/8+4 = 20/3

but i don't know which one i am supposed to add first, because 1 and 3 are in parallel, and 2 and 5 are also in parallel, so do i add those first? I don't get the order..
