Frequency applied to Cap & Inductor

Click For Summary
SUMMARY

The discussion focuses on the application of a 1kHz frequency to a 1000 μF capacitor and a 10 H inductor. The capacitance of the capacitor is confirmed to be 1000 μF, while the reactance of the inductor is calculated using the formula Xl = 2πfL, resulting in 62.8KΩ. The user initially miscalculated the capacitance as 159 fF, indicating a misunderstanding of the concepts. The forum provides clarification and resources for further learning.

PREREQUISITES
  • Understanding of basic electrical components: capacitors and inductors
  • Familiarity with frequency and reactance concepts
  • Knowledge of the formulas for capacitance and inductive reactance
  • Basic skills in using mathematical equations in electrical engineering
NEXT STEPS
  • Study the formula for capacitive reactance: Xc = -1/(ωC)
  • Learn about inductive reactance and its calculation using Xl = 2πfL
  • Explore the relationship between frequency, capacitance, and reactance in AC circuits
  • Investigate resources on complex impedance and its applications in circuit analysis
USEFUL FOR

This discussion is beneficial for electrical engineering students, hobbyists working with AC circuits, and professionals seeking to deepen their understanding of capacitors and inductors in frequency applications.

1. The problem statement

1kHz is applied to 1000 μF Capacitor, What is its Capacitance?
&
1kHz is applied to 10 H inductor, What is its reactance?

The Attempt at a Solution


using
x= -1/ωC = -1/2∏∫C
I came up with 159 fF

then for question 2 I got
using
Xl=2∏FL (better seen here http://www.raftabtronics.com/portals/0/EquationImages/XsubL.png )

and I got 62.8KΩ

my problem is this.
i tried learning it myself but this forum https://www.physicsforums.com/archive/index.php/t-35071.html confused me a little bit. So to make sure I am on the right path, I am posting on here yet again...and I am sure there will be more to come after this.
