Mostly been a software person for a while.

I used to have lots of experience with 3 phase

It’s been a long while since I messed with DC power.

Question:

If you have say a simple RC circuit that is a complex impedance

And you put DC through on it, is there any reactive power? Is it all watts?

I am trying to recall the rules

Now logic tells me that at steady state, the cap is going to have infinite impedance

So is it consuming any power?

How can we prove this?

Thanks in advance
