I am confused on how a transformer works. I know it uses a changing magnetic field to induce current into another coil that has a set turn ratio to achieve a specific voltage.
My question involves the current draw of a transformer. I understand that a wires resistance is very small and coiling it does not change its resistance. So how does the transformer not trip the fuse every time it's plugged in.
I have tried creating a primary coil before and have only had two results: I trip the fuse, or my coil starts on fire...
Could someone explain to me how I am able to make a coil not draw too much current?
