Solve this problem, formula conversions

Inductive reactance(XL) = 6.28*(f)frequency*(L)inductance

Transpose and the show formulas for Frequency and Inductance, show your work.

Inductive reactance (in ohms) is linearly proportional to frequency.

Not sure what you're looking for other than

f = XL/(L* two pi) and

L = XL/(f * two pi)

Or Charles will do your homework. That's really nice of him. You aren't learning a damn thing in the process so even though Charles thinks he's doing you a favor and you appreciate the opportunity to be lazy, you'll be embarrassed the first time you need to actually do your own research at a job and don't have a clue how to go about it.

Since it says "SHOW YOUR WORK" you have to bring Charles to class with you...

I helped many a coed with their math and engineering homework and labs in my college days.

It paid off.

If you use 6.28 to equal 2pi your calculations can be way off, the higher the frequency the higher your error can be.

To rearrange use a KNOWN equation like 24=2*3*4 as a primer
