It wasnt complicated, I went wrong some where just wanted to know where.
Now on with inductive reactance.
(taken directly from the ARRL handbook)
XL=2pi F L
So, if I knew the voltage (AC) and the current, I could find XL Correct? But would the XL found using V/I be the same as XL =2pi F L?
So Then once I have XL I could rewrite the formula to find L so that:
L= XL/2pi F
EDIT: I have also read on how to measure inductors, but I get weird values. The circuit consists of an unkown inductor in series with a known resistor, R. Voltage is 18vRMS, but the resistor takes up most of the voltage and I measure a very small voltage across the inductor (0.05V). Shouldnt the voltage be greater? Or does it matter on which polaritys I measure the voltage of the inductor with? Btw I used a 1K resistor. Im thinkings of making it smaller.
Like everywhere in the world, the intelligence of people vary as do their learning capacities and everything else. If you compare the EC kids from 1 area to the validictorians of another area, of course the validictorians will look smarter.Originally posted by kubeek@Oct 4 2005, 08:27 AM
OT: In the school we just talked about education in usa. Teacher told us it is not on very high level.
So: Do you (all) consider this equation and solving L to be complicated, or it´s just a bad example? (I mean no offense
