Inductor impedance explanation

[levnu]

Hi to all,

if i'm using an inductor with jwL impedance:

What its impedance effect is?
- in high freq i see high impedance?
- is it ohmic?
do i have losses of power like it was a huge resistor?
or it just high impedance that is unlike resistores gives back the energy?
- in low freq does it mean that i see very low ohmic resistense or very low impedance which is not ohmic?

as you can see i'm confusing between ohmic, resistive & reactive impedance.

Thanks a lot

Hi;
In hi freq you should see reactive impedance.
Ohmic and resistive (or DC resistance) should be the same thing and it depends on your coil number of turns (copper length) and copper cross section.
Reactive impedance does not have ohmic behaviour. Consider that; when you pass a sine wave over ohmic resistance, its phase doesn't chage, but in case of inductor there will be a phase shift in the signal (current would be lagging)...
Hope clears your mind...

Thanks a lot

And now the question is
over ohmic resistance there is loss of power
what happends over reactive impedance there should be some loss too isnt there?

i mean 1ohm of resister loss power,= to 1ohm of impedance loss power>?

Ideal reactance is lossless.

thanks thats what i wondered about...
