It can now be demonstrated that the LED does not light directly from the battery. I offer 2 options: 1 - short with fun music, 2 - longer with explanations To tell that even though the battery is AA, but unusual, not 1.5 volts, but lithium 3.6. First you need to clarify that a standard "finger" AA battery produces 1.5 volts. Next, we need a piece of wire 30 centimeters. 11. Not every battery can do this. Usachev, A. I took an ordinary copper cable 1.5 mm2 and freed one core from insulation: Now is the time to “be smart”, tell about the oscillatory circuit, about the world anti-Ether conspiracy, etc. Now it remains to bend the legs of the LED, observing the polarity and calculating the distance from the " " contact to the LED by the size of a carbon tablet: It is possible not to cut if it is difficult, but mechanically the final construction will be somewhat more difficult: 4. From the resulting piece of copper wire we make a coil of any size. 5. It will not make a trick of the impression: one half of the audience will simply say that what the heck, well, he took a one and a half volt diode, https://jiji.co.tz/cars/toyota-mr2-spyder that's business. 6. © A. And now the most important thing is to tell the essence. It looked impressive. Hello, inspired by a recent post about "perpetual motion", I remembered one video on the Internet, where one craftsman "set fire" to an LED from AA batteries using a coil of several turns and activated carbon tablets. 2. 1. So that even thoughts about the “miracle” do not remain, because children must definitely develop critical thinking. I wound it right over the battery: 8. To do this, demonstrate the inscription on it, as well as the luminosity of the LED without any tablets, magnets and coils: I used the first option. So I decided to make a homemade product in 3 minutes. Entertaining the younger generation
Children are a perpetual motion machine, a jumper, a runner, a pusher, a jumper, a grabber, and also a tight hug and a kisser 9. Although https://tonaton.ug/s_142-tiling-services the solution is quite easy to read.
