Light bulb - have an idea!

Electric lighting is an integral part of any home. The modern world cannot be imagined without the various types of light bulbs that give us light.

A light bulb is a closed and completely sealed glass vessel that has a pear-shaped shape. In truth, now there are many forms and principles of operation of bulbs, but in this article we will talk about the usual "Ilyich bulb" with a filament. She received this name thanks to the mastermind of electrification in the Soviet Union.




The first filling lamp was invented in 1809 by the Englishman Delar. But then it had not a tungsten, but a platinum spiral of a completely different shape. And the first tungsten filaments appeared 100 years later in 1905 in Hungary. The principle of operation of the bulb is the flow of electric current through the body of the filament, which heats the inert gas inside the glass vessel. Gas, under the influence of high temperature, emits in a wide range, including visible light. There are many types of light bulbs: local lamps, mirror incandescent lamps, spotlights, lamps for optical instruments and many others.

From old bulbs you can make various crafts: original plant vases, Christmas-tree decorations and decor elements. This is possible due to the properties of this material for crafts. Firstly, you can draw water into the container. Secondly, transparent glass makes it possible to see any filler that you want to place inside (for example, sand or pebbles). You just need to follow the instructions and tips that you will find on the website in various articles about crafts from light bulbs.

Surely beer lovers know that the famous Oktoberfest was first electrified in 1886. These works were carried out by a company that belonged to Einstein's father. And Albert Einstein himself screwed bulbs in the seller’s beer tent by the name of Schottenhammer.

At the end of the article I want to give a very interesting riddle about light bulbs, only real ones the inhabitants of our site will be able to cope with it and write their own answer options (there are several) in the comments:





In a closed room in the attic are three bulbs. Three switches to three bulbs - downstairs, on the first floor. You can click the switches as much as you want, and you can leave them in any position. But after that only one trip up is allowed.

Question: How to determine which switch each lamp works from?

Quote: "one light bulb can be tortured to burnout"
And how do I know that I’ve already been tortured?
1. Do not turn on the first switch!
2. Turn on the second for a couple of minutes, turn off the loan.
3. Third turn on and quickly climb to the attic.
The first lamp is cold, the second is warm, the third is on.
Can you find out the correct answer?

Turn off one light bulb, go up and see which one is off - it is clear that it is from the turned off switch. Then unscrew (or break :) one of the BURNING bulbs. Go down and check which switch turns off the whole light bulb. With the third switch, it becomes clear.
Hmmm ... It sounds a bit like a challenge for my analytical capabilities and practical skills: wink:
If you click an unlimited number of times, then one light bulb can be tortured to burnout and leave one on and one off, in the end we will see one burning, one not burning and one burned out. How is this solution? : belay:

I re-read it again and thought about another option, you can “highlight” one bulb by attaching resistance to the switch and then the bulb connected to it will burn to the floor. : winked:
Well, for example, turn on two switches and go up. Two are on, but one is not. With non-burning everything is clear, but those who are on fire chances to guess 50% to 50% - you can play))))))
