I know this question is prolly stupid and with a simple answer but I just can't figure it out.
Well, the electromagnet, which is basically what changes the voltage and current. It is said that you can lower the current by raising the voltage and vice versa. I know WHY they do it, but what I don't understand is how can highering the voltage lower current?
I=U/R
R stays the same
I changes according to U
U is raised
"I" should raise too.
I would completely understand when lowering the voltage would lower the current and vice versa.
This prolly a very stupid question so I understand all the "lolling" but I need to know hte answer.
Thanks in advance,
