A pile and a tangerine have something in common
A battery and a tangerine have something in common: their round shape. However, their uses and characteristics are completely different. Discover more about these two keywords in the following text.
How to make a pile with a fruit?
Citrus fruits are excellent conductors of electricity due to their acid content. When a galvanized or zinc nail is inserted into the fruit, negatively charged ions or electrons begin to transfer from the fruit to the nail, leaving the protons in the fruit. This transfer of electrons generates electricity, allowing a light bulb to be lit by connecting the wires to the nail. It’s surprising, right?
What happens if I touch a burst battery?
I found some batteries already sulfated and I don’t know if contact with that dust is bad for your health. Only contact with these batteries does not cause problems for your health. I would simply recommend maintaining minimal contact, washing your hands very well and disposing of them in special areas designated for batteries of this type. Thanks for consulting. If the answer was useful to you, I suggest you mark it as such and tell us about its usefulness.

The Integrated Contribution Settlement Form (PILA) is a format that allows companies and individuals to pay and settle the contributions required by the Social Protection System. This includes health systems, occupational risks, pensions, compensation funds, ICBF and Sena. Payment of the PILA is mandatory and failure to comply may have serious legal consequences.
In this article, we will explain everything related to the PILA, from its composition to the payment dates and the actions that can be taken after making the payment. For more information, click here.

Types of batteries
Batteries are essential for any device that requires power. They can be classified according to their shape, size or composition, but in general they are divided into two main groups: rechargeable batteries and non-rechargeable batteries.
The way batteries work consists of converting chemical energy into electrical energy, so it is important to recycle them correctly due to their composition.
Each type of battery is suitable for a different device, but we often don’t know which type of batteries to choose. On our website, you will find the alkaline batteries you are looking for.

How does a battery with lemons work?
In Natural Science class, sixth grade students learned about how batteries work by generating electricity using two lemons. A lemon battery produces electricity through a chemical reaction that occurs when metals are introduced into the lemon juice. Because lemon juice is acidic, it helps break down the atomic structure of metals like copper and zinc, releasing electrons that generate electrical current.
Professor Guisela Garrido, in charge of the subject, mentions that this was a different and very fun experience for the students, where they learned in a playful way how batteries work.
What is the voltage of a lemon?
Lemons have an electrochemical solution inside that allows them to generate a small amount of electricity, specifically 0.85 volts. To light a 3 volt LED, we will need to use four lemons. In addition, we will need copper wire, zinc-galvanized nails, alligator cables and some pliers.
The procedure is pretty easy. First, we cut the copper wire and wound it around three of the nails. Next, we poke the copper and zinc into all the lemons to create a series circuit.
Finally, we connect the zinc nail, which is our negative pole, to the short leg of the LED, and the last copper electrode to the long leg.
I hope my fruit girl is seeing this and understands why I ordered a large quantity of lemon stacks from her yesterday.
What happens if a child bites a battery?
Batteries are common objects in our daily lives, present in remote controls, watches, toys and other electronic devices. However, it is important to note that these small batteries can pose a danger to children if ingested.
Batteries contain toxic chemicals such as mercury, lead and cadmium, which can cause serious harm to children’s health if ingested. Symptoms can range from irritation in the throat and esophagus to burns in the digestive tract and perforations in the stomach or intestine.
It is important to note that not only large batteries are dangerous, but also button or watch batteries represent a risk to children due to their size and shape. These small batteries can get stuck in a child’s throat, causing choking or damage to the vocal cords.
Therefore, it is essential that parents and caregivers are aware of the danger that batteries pose to children and take preventive measures to avoid ingestion. Some of these measures include keeping batteries out of the reach of children, not leaving loose batteries in the home, not allowing children to play with batteries, and teaching children not to bite or suck on batteries.
What was the first stack like?
Alessandro Volta, renowned scientist, carried out important research throughout his life. Among his achievements are the discovery and isolation of methane gas, as well as the improvement of the electrophore invented by Johannes Wilcke, a device that generates static electricity. However, his greatest contribution to science and humanity was the discovery of the voltaic cell. In the 18th century, knowledge about electricity was scarce and focused mainly on static electricity. Volta became interested in the work of Luigi Galvani, who observed that the contact of two different metals with the muscle of a frog generated an electrical current. Volta experimented with metals and concluded that muscle tissue was not necessary to produce electrical current. In 1800, he made the first successful demonstration of the operation of the electric battery, composed of silver and zinc discs separated by cardboard discs soaked in brine. This battery generated a constant flow of electrical current, unlike the Leiden bottle which discharged all the stored electricity at once. Thanks to this invention, physicists were able to work with controllable electrical currents. In addition, it was discovered that the electrical current from these batteries could decompose water into hydrogen and oxygen, opening a new field of scientific research.
