First off, I just want to say thank you for any help! Also, I ask that if you can, please try your best to explain this to me in layman terms. I understand ohm’s law and I have a decent grasp on electricity, so I don’t need water analogies. But I’m not very smart and i just love to learn how things work without really complicated equations. I don’t mean to sound demanding; i’m just requesting this sort “dumbed down” answer.
I have researched the internet for hours trying to understand this. I’ve heard time and time again that the magnetic field of an inductor and transformer are directly related to the amount of current in amps (obviously there’s the number of turns, surface area, core, etc.. as well, but I’m talking electrically). They also say that increasing voltage (assuming resistance stays the same) will increase current, and that’s the only reason that voltage would help supply the magnetic field with energy (or magnetic flux).
So here’s the thing. That doesn’t make sense to me. Why? Well for one, if you have 5 volts dc connected to a 5ohm circuit (setting aside an inductor’s initial impedance) , 1 amp of current flows. Now, if you have 20 bolts and 20 ohms, 1 amp flows. This means that in scenario 1, there are 5 watts of power. In scenario 2, there are 20 watts of power. So when an inductor initially charges up, there’s a high voltage drop across it..so unless that potential is being wasted, it must be giving power to the inductor.
Next, in an IDEAL transformer, if you have 1000V with up to 10A current in the primary, then step it down to 100V at up to 100A in the secondary, this means that it’s not just the current flow in amps that allowed the magnetic field from coil 1 to coil 2 to produce this power. Why? Because obviously the power, which is voltage x current, was saved on the second coil. So how then, could the magnetic field only be related to the amps of current and not the voltage (or maybe kinetic energy of the electrons if that’s what voltage “turns into”)?
If anyone could help me, again, I’d be really appreciative. Im not the best at explaining my questions sometimes, so if you need any clarification, please ask me.
Sorry for the long post. I didn’t mean for it to be this long.
