Question:

I took a transformer out of an old radio i want to use it as a shocking device?

i took it out. on one side of the transformer i have a black and a red im hooking those up to a battery on the other side i have five wires 2 red, 2 white, and 1 blue i dont know what these do or how to get current to them. does anyone know how to complete the circuit???

Answer:

The transformer you have is specifically a low voltage AC transformer. You will need an digital multimeter to measure the resistance off the wires - 1 white + 1 red resistance in ohms. If no resistance off to the next pair. Also do a product code search. Who makes the transformer? You could do a parts search online and find out who makes it and how it should be wired. Running an AC transformer can be done with DC current - but it cannot be done through just a battery cell. Remember that natural DC current has no flow or cycle rate. Therefore it is at 0 Hz. So if you applied a battery cell to the transformer with natural DC as soon as you touch the wires you'd get voltage but that would be it. Nothing after that unless. You had pulsed DC current. Pulsed current via 555 timer is usually in the kHz range. This causes the AC transformer windings work like they are suppose to To get this to happen you must special circuits to change frequency. You can look up these plans online and find great tutorials on building plasma globes and such. Look up 555 timer high voltage power supplies. Very cheap and easy to make. I'd be careful making any kind of shocking device. Know the laws of your country first before making something that is designed to shock.
A battery puts out only DC, and a transformer needs AC, so this will not work. Do NOT try to build a shocking device, you are too young to spend years in jail. It's impossible to pick a voltage that is felt as a shock by some people without killing someone else. .
You're already dead in the water trying to make a transformer work with DC power. You'll need AC, or at the very least pulsating DC.
Heck no, there is no way I would take my 4 year old son who LOVES Transformers (no idea why he loves them, he's never even seen the cartoon, just has the toys). I took him to see a PG rated movie Saturday (Up) and regretted it b/c I'm still not sure it was appropriate for his age (he was very scared many times throughout the movie and put his head under my arm to hide).
You are trying to duplicate the Kettering ignition. Momentarily touching a battery to the lowest ohmage winging will usually get you a spark from one or more of the other windings. The old (my era) radios had a secondary to produce high voltage 400-600 volts (often centertapped) and a filament winding 5-6 volts. You would touch the battery to the filament winding and get the spark from the 4-6 hundred volt winding. If you used 110 volts ac on the black and red wires you would get a continuous 4-6 hundred volts AC from the secondary winding with enough amperage to kill someone.
