Hi there,

I need help transposing the equation for electrical resonance.

The equation is f = 1 / 2*pi * squareroot of L*C

I need to make C the subject, any help would be greatly appreciated.

Now

*this*is ambigious. Pick the right one :

$\displaystyle f = \frac{1}{2} x \pi x \sqrt{L(x) C}$

$\displaystyle f = \frac{1}{2} x Pi(x) \sqrt{L(x) C}$

$\displaystyle f = \frac{1}{2x} \pi x \sqrt{L(x) C}$

$\displaystyle f = \frac{1}{2x} Pi(x) \sqrt{L(x) C}$

Or just edit your post with the right one. Use the [tex] tags to write it in LaTeX with the pretty symbols and all.

**EDIT**: ah you edited it somehow before I posted. Well, as TkHunny said, just use division/multiplication/squares to put this in order :) - Feb 26th 2010, 01:50 PMTKHunny

Is C part of the radical or not? Also, is everything after the / sign in the denominator or is it (1/2)(pi*...)?

From the actual question we get

$\displaystyle \omega = 2 \pi f = \frac{1}{\sqrt{LC}}$

Manipulating to get f we get the original question

$\displaystyle f = \frac{1}{2\pi \sqrt{LC}}$

Multiply by $\displaystyle 2\pi$

$\displaystyle

2\pi f = \sqrt{LC}

$

Square both sides, then divide by L

$\displaystyle C = 4 \pi ^2 \cdot \left(\frac{f^2}{L}\right)$ - Feb 27th 2010, 11:41 AMnleadbet
