## Homework Statement

Now demonstrate how to calculate resonant frequency. Calculate the capacitive reactance for a 300uF capacitor in series with a 800mH inductor.

## Homework Equations

f = 1/2pi(LC)^1/2

Xc = -1/2pifC

Hi

I urgently need this solution checked out for my BTech deadline. The question reads thus:

## The Attempt at a Solution

where L = 800mH, C = 300uF

so,

f = 1/2pi(800 x 10^-3 x 300 x 10^-6)

So, f = 10.3 Hz

so, Xc =-1/2pi (10.27 x 300 x 10^-6)

Will my final answer be expressed as a negative?

Any suggestions will be appreciated.

Thanks a lot in advance.
