I found a fairly big, old transformer. I unwinded all the coils and winded them again. My primary coil has 20 turns, and the secondary coil has 200 turns. I didn't use any tools while doing this, so it isn't precisely woud.
Now, when connecting this transformer directly into the power outlet, the power fuse goes out. I have 3 theories for why this is happening:
- Maybe I shouldn't connect the transformer directly into the outlet - do I need to put something "in between" the transformer and the power outlet?
- Maybe I am connecting the transformer in a wrong way? Currently I connect it by putting first primary coil wire into first hole in my power outlet, and second primary coil wire into second outlet hole.
- Is it possible that there is something wrong with the wires? I put isolation tape all over the primary coil so that those two won't touch.
What is wrong with my transformer?
