I don't quite understand your problem. What is the value of Vs? Assuming I understand correctly that it is 5V, then the bias point of your voltage divider at room temperature is 2.5V, which is within the range of your nRF reference of 3.6V.

And to add to the other answers, if the voltage difference is too large, you can have an electrical breakdown of the medium between the two "ends" of the open circuit and so a temporary circuit where current flows through: en.wikipedia.org/wiki/Electric_arc But this is a very specific case.

Is this for educational purposes? Otherwise you would be better off buying an IC that does the job for you.

No it's not RU-Recognized and we cannot change the design unfortunately. Is either UL 1642 or UL 2054 really needed for the US? Is IEC 62133 not enough?

I am using only SMD components. There doesn't seem to be a pattern on the components that are wrong, however they are grouped according to the footprint (so for example, all SOT23-5 components are off by 90° degrees.

That's actually quite helpful. Probably means I will have to stick with one standard for my components and manually rotate them for each fab house. I know they do their AOI and also manual checks, but just to be 100% certain each time.

@CFCBazarcom No I am using a 4-layer PCB. Which setting are you referring to?

@winny I think I can safely assume that energy as a concept uses the active power and only the active power for its calculation. So I will just stick with this for my purpose.

Thanks for the answer but I feel it does not fully answer my question. If you see I am asking about the relation of the energy to the different definitions of power, as I can say I understand the concepts of power fairly well (well, as much as one can understand them maybe), but not how exactly they translate into energy.

@Chu for clarity, VA is the unit for apparent power and VA-reactive is the unit of reactive power.
