My story of High Voltage in Wire

[Primarygun]

Wanna share an interesting thing with you, so I started this thread.

It seemed that I used to know and understand reason for the introduction of high voltage before entered the magnetism.

Today, when I had a read on a thread in another forum, I strived to recall my memory again.

Then, I found myself totally confused.

May I tell you my confusion.

[Math]P=VI [/Math]

V increases, then I decreases.

[Math] Power loss=I^2 R[/Math]

I used to this approach for the interpretation.

Today, I was reminded of thinking it in the V way.

[Math]Power loss=V^2/R[/Math]

Voltage is indeed increased, according to the equation, Power loss should increase accordingly. However, the fact in reality rejected this explanation.

If you don't know the reason behind at this moment, please try hard to figure it out on your own.

Try to think of a circuit with some resistors.

 

 

Then, I remembered the magnetism.

Power Input=Power loss+ Power output.

Increase the voltage indeed decreases the current.

But the fact here is, this is not a simple circuit, it is connected to a transformer.

so, voltage supplied by the primary transformer(Emf) is not totally distributed to the resistor. Some of it is used for generating another magnetic field.

I don't know whether I'm correct, but at this moment, I think I could think of a question scientifically.
