SUMMARY

The discussion focuses on solving for the variable C in the formula Xc = 1 / (2πFC). The user seeks assistance in manipulating the equation to isolate C, which is achieved through algebraic rearrangement. The correct formula for C is derived as C = 1 / (Xc * 2πF). Additionally, the user expresses a need to solve for F, indicating a desire for further clarification on both variables.

PREREQUISITES
  • Understanding of algebraic manipulation
  • Familiarity with mathematical constants, specifically π (Pi)
  • Basic knowledge of electrical engineering concepts related to capacitance and frequency
  • Experience with formula derivation and rearrangement
NEXT STEPS
  • Research algebraic manipulation techniques for isolating variables in equations
  • Study the relationship between capacitance (C), frequency (F), and reactance (Xc)
  • Learn about the significance of π in mathematical formulas and its applications
  • Explore practical examples of solving for unknowns in electrical engineering formulas
USEFUL FOR

This discussion is beneficial for students and professionals in electrical engineering, mathematicians, and anyone involved in solving equations related to capacitance and frequency in circuits.

This is the first time I've used this forum and i really could use someones help on how to solve for C in my formula instead of Xc

My formula is

Xc = 1 / (2PiFC) "Pi is, pi yea know, 3.14", (not 2 other unknowns)

Instead of solving for Xc i need to be able to solve for C and i don't know how to go about doing that...

any sort of help would be appreciated :)

Also... i looked down the page alilbit and i also need a formula on how to solve for F

If someone could show me how that's done so i wouldn't have to ask anyone anymore i would be very happy.

do you mean you want C on the left handside of the equation? manipulation of equation?

PS: i believe the admin will do something about your posts because they are duplicates. They will say something like 'Please do not cross-post' or ...; move or delete your posts.

Make C the subject of the equation. That can't be too hard, surely?

Xc = 1/2πfC

=> 2πfCXc = 1

=> C = 1/Xc2πf

Where's the problem?
