I'm straying off the path by having to look at an electrical problem. I was hoping you guys might be able to point me in the right direction since it has been a long time since I have done anything like this. I'm hoping I'm having a serious brain fart and it's nice and easy.
What I have is a coil of some set resistance (the coil is being used as a resistive heater element). I have a DC power source feeding the coil. Dealing with the calculations in the DC realm is straight forward. No issues there. However, I was asked about the coil's impedance as well. So, I am assuming that, because the word "impedance" was used, that they are referring to a probable AC component coming from the PS. Is this a safe assumption?
Also, if my PS has a ripple spec of, say 10%, how would one calculate the AC component of the output based on the 10%? It's a 3Ø AC input.
Thanks for the help
