Maybe a not well thought out question:
https://cdn.automationdirect.com/static/specs/78relays.pdf
781-1C-24A Relay is listed as having ##177 \Omega## Coil Resistance. I'm assuming that figure will give the Real Power dissipated by the coil (entire relay circuitry) for some current ##I##, or some voltage ##V_{ac}## across its terminals?
Just an ME here, my circuits knowledge is a little rusty, small, and minimally applied. Be Gentle!
I'm confused, because I was under the impression that coils didn't consume real power. They consume reactive power. So I'm assuming the manufacturer is referring to the resistance in the circuitry of the entire unit., not the "coil" per se?
