ok so I was creating a connection today and used a 5 v led on a 1.5 v battery. Battery was in a case from radioshack and had insulated leads, full of twisted micro wire. Since there was no way to crimp it or strip the wire without me ruining the twists, I just bundled it to some non twisted wire and crimped it with aluminum foil. So I made an aluminum foil circuit with copper wire. The voltometer measured a steady 1.4 volts. There were a total of 4 aluminum foil crimp terminals, and the voltomer reads were good on all of them, 1.4 volts. (The voltometer completed the open circuit.) So I connected the 5 v led to the last 2 terminals, and the led didn't light. Yet, the LED completed the circuit, I touched the voltometer leads to the LED leads not the aluminum foil terminals. So the led was either defective or did not light at all with 1.5 volts. It was one of those flashing led's. I turned the lights off to verify...no light, a lightbulb did not light either. So I am going to have to buy a led rated at 1.5 volts. But other than that, all and all was good with the circuit, until... i then attached a 12 foot long insulated thin copper wire to it. Can't remember the gauge, it was the thinnest I could find though. All of a sudden things went haywire. In order to test it, I stripped some of the insulation, past the 3rd and 4th aluminum foil terminals. I attached the voltometer leads to the 12 foot long wire. Readings were erratic, and the battery started to heat up. Readings fluxed from 0.1 to 0.3 volts. Behavoir exhibited a strange pattern. The further I got from the battery, the more the voltage dropped. The closer I got, the higher the voltage. This was bewildering, because it occured even imbetween the original aluminum foil crimp terminals! It should have short circuited and became like the original model, yet instead of behaving like the original model, where all aluminum foil terminals measured 1.4 volts, this time the 4th and 3rd has less volts because they were further away, and the 2nd and 1st had more volts than the 4th a 3rd terminals, but still not as much volts as directly touching the battery, the voltage behaved as a proximity value. For instance, even at a close range, moving the voltometer leads a few inches closer to the origin would increase the voltage by a high value, the closer it got to the battery. This was bewildering, because it did not behave like a short circuit, which should have reverted its behavoir to the original model. I had to end the experiment short because after adding the 12 foot wire, the battery was heating up and losing voltage at a rapid rate. Does anyone have a explanation for this phenomenon? Also, close to the terminal the 12 foot wire was wrapped around a screw about 30 times. No discernible magnetic force was generated, as expected. I will post a picture diagram of the experiment, if need be.
