Even though I have already seen the theory behind transformers, at that age I didn't really know what was going on and probably missed this explanation.
When you connect a load in parallel with an Active Independent Voltage source (If I'm correct) if you increase the voltage of the source the power drawn by the load will increase as well (since the current increases).
Now, if you connect a load to the output of a transformer which is a passive component, I've been told that the more you step up the voltage the current will automatically go down so S = VI (all in magnitudes) remains intact. I was told that in the power transmission lines course.
Question 1: If this is true, then for a known fixed load, If I connect it to a 400V, 200V, or 500V transformer output, it will draw exactly the same S?
Or maybe it will draw the same P but a different Q?
Question 2: If this is true, how does the input voltage (transformer's output voltage) affect the load?
A: "The power drawn is only dependent on the load". This is what I've been told...
B: But I believe that "The power drawn, depends on the load and its input voltage".
