I would like to wind a custon transformer.. It will operate at about 50-60Hz, and I will be using the coil former and core from an old mains transformer. Now, my question is, how many windings to I need. I want to switch the car voltage, (so it is AC) them step it up by about 20%. so, teh transformer will be 1-1.2..... the question is how many windinds do I need on teh primary/secondary... I know HOW to work it out, but want to know how many windings or turns I need, so it will work, and be safe/efficent... would say 50turns on the primary be alright?? AARON!!! HELP ME!!!!!
