A voltaic pile, as the name suggests, is actually a "pile", which is composed of "voltaic layers" stacked one after another.
Richard put a zinc ring on a copper ring and pressed it with a piece of linen soaked in salt water to create a "voltaic layer". Next, Richard put the zinc ring and copper ring on the linen cloth again, and pressed the linen cloth. Repeat the operation more than a dozen times, and a columnar body will stand in front of you, which is the so-called "voltaic pile" - the most elementary battery - with the negative electrode on the top and the positive electrode on the bottom.
Without hesitation, Richard quickly connected the metal wire and felt the current strength of the voltaic pile. His eyebrows raised slightly at first, and then calmed down.
It is true that compared with the fruit battery, the current of the voltaic pile has indeed become stronger, but the intensity is limited, and there is no change in magnitude (ten times).
Of course, if you want to forcefully use this kind of voltaic pile, it is not impossible. If the current is too small, it can be increased by "parallel connection" of voltaic piles, and if the voltage is too small, it can be increased by "series connection" of voltaic piles. This is just the application of junior high school physics knowledge on modern earth.
But one problem that Richard has to face is that the current and voltage of the voltaic pile are insufficient. If you want both to meet the standards, you must connect them in parallel and in series to form a huge voltaic pile." phalanx". This current was used during meditation. Richard doubted whether he could have enough voltaic piles in his bedroom.
So... it still doesn't work.
Richard took out a breath and frowned deeply.
The two maids looked at Richard in fear. Richard kept frowning and thinking, and after a while he tried again on time.
Since fruit batteries don't work and voltaic piles don't work, then let's make a Baghdad battery.
Yes, Baghdad Battery.
If the voltaic pile is the first recorded generator on modern earth, then the Baghdad battery is the first unrecorded generator on modern earth.
Unlike the rest of the batteries, the Baghdad Battery has no clear inventor; in fact, it was dug out of the ground by accident:
In the history of modern earth, one day in the midsummer of June 1936, outside the village of Gagatrabua on the outskirts of Baghdad, the capital of Iraq, the railway construction project was in progress. When the workers were preparing to lay the roadbed with shovels, they unearthed an ancient mausoleum made of huge stone slabs. They continued to dig and dug out an ancient sarcophagus.
Two months later, with the help of Iraqi archaeologists, the sarcophagus was carefully opened and a large number of cultural relics from the ancient Persian era more than 2,000 years ago were discovered. There are twisted beads composed of pearls, a large number of gold and silverware, and a piece of weird-shaped pottery.
This pottery was the Baghdad Battery. After it was successfully repaired, the current generated lasted for 18 days before disappearing.
No one knows why chemical batteries existed more than two thousand years ago and were more advanced than voltaic piles. No one knows how advanced electrical experiments were at that time.
Richard also didn't know this puzzle. Now he made the Baghdad battery, just to test whether it could meet his needs.
hope so…
Richard thought, turned around and gave instructions to the two maids again. This time it took a little longer because the materials used were obviously much more troublesome than the previous two batteries.
Half a day later, the materials were ready and Richard started making it himself again. The two maids watched with wide eyes, because they didn't know whether Richard would let them look at it once and then imitate it and make a new one. After all, there was a precedent for this.
Richard moved quickly. He first picked up a clay pot with a height of more than ten centimeters, and then poured the sticky asphalt into it.
The asphalt still carries temperature and maintains a certain degree of fluidity, slowly deforming according to the shape of the clay pot. After the asphalt filled most of the pot, Richard picked up a thick copper pipe with a diameter of about 3 inches. Insert it into the asphalt in the can so that the entire copper pipe is submerged in the asphalt.
Then Richard picked up a thin solid iron rod and inserted it into the copper pipe, carefully controlling the angle to ensure that the iron rod did not touch the wall of the copper pipe and was several centimeters higher than the copper pipe.
After doing this, he immediately started pouring the acid into the jar. When bubbles appeared, the Baghdad battery was completed. Connect the copper pipe and the iron rod with wires, and when Richard touches them, he immediately feels a much stronger current.
But after feeling it for a while, Richard frowned again.
It is true that the current is strong, but it is still not enough to change the biological current in the body. In addition... the current of the Baghdad battery is extremely unstable, sometimes strong and sometimes weak. Although it is not clear what impact this will have on "opening up the source of law", Richard feels that it should be a bad one.
"As expected, it still doesn't work." Richard murmured, exhaling a filthy breath. Shaking his head, he opened the door of the independent laboratory and walked out. The maid Angel and the maid Luna quickly followed.
The other maids in the hall saw Angel and Luna still together with Richard, and couldn't help but cast jealous glances at them. But soon, they discovered that Richard, the prince, had an unhappy expression on his face. An Qi and Luna were even more flustered, and their eyes immediately turned into gloating.
There is also competition among the maids, and it is very fierce. At this moment, in the eyes of the other maids, Angel and Luna obviously did not complete the tasks assigned by Richard and made Richard angry. This is good news for them.
"Da da da da", Richard walked through the hall and walked to the palace door. He found that it was almost afternoon - half a day had passed before he knew it.
After three experiments, the current problem is still not solved. How to solve it
Richard fell into deep thought.
Guards Captain Edward appeared. After seeing Richard, he originally wanted to remind Richard not to forget to eat lunch. But seeing Richard's brows furrowed and deep in thought, he stopped rationally and did not come to disturb him.
The whole world suddenly became quiet. The guards and maids in the palace were busy doing things, trying not to make any noise, for fear of affecting Richard's thinking and making His Royal Highness angry.
In this strange silence, Richard thought for a long time, looking for a solution to the problem.
After a while, Richard suddenly raised his head and looked at the square in front of him.
"Thumping, fluttering..."
Two gray finches flew almost close to the ground of the square.
Turning to look above the palace door, in a corner, a spider was weaving a web quickly, a vertical web.
Narrowing his eyes slightly, Richard stretched out his hand and felt it, and found that the humidity of the air was increasing. I turned my head and glanced at the sky. The sun was still there, but the clouds were thickening, and the sky in the south was getting darker.
"Is it going to rain?" Richard narrowed his eyes.
Theoretically, this is normal. After all, it has been hot and dry for several days, and a large amount of water vapor has evaporated into the air. There is a high chance of rain. From the looks of it, it should be pretty heavy.
And once it rains, it will be accompanied by thunder and lightning.
Thunder and lightning, as a natural electric current, are theoretically strong enough to change the biological current in a human body without even thinking about it. But how to draw it down and control its use is a problem. After all, I don't want to be struck by lightning. That would not be scientific research at all, but suicide.
In this case…
After a moment, Richard turned around, had a plan, looked at the guard captain Edward and said: "Find the craftsman from the palace, I have something to tell him."
"Well, it's..."
