"Not enough energy."
Avesta looked thoughtful.
Very clearly, the most difficult to solve situations appear.
Because of copying Ambrosia, the USB has run out of energy, there is no way to copy anything else again.
However, Avesta also received good news.
Of course, the word "Not enough energy" may appear, so it can be proven that the USB can be supplemented with energy.
As long as things have not reached the worst level, there is still a chance.
Just, this USB, what kind of power source does it need?
Avesta stared straight at the gloomy ancient USB in front of her eyes, and suddenly her mind stirred.
She walked to the dormitory door and looked up.
An ic card electricity meter embedded in the wall.
Because this place is located on the coast, often need to use air conditioning. Therefore, the dormitory of Shangdu University does not restrict high-power electrical appliances.
However, each dormitory has an electric switch, the total power is limited to around 10A.
At this time, the electricity meter shows that there is still 52.65 kilowatts of usable electricity in the electricity card of dormitory 404.
Amount of electricity?
Avesta turned around and took out the laptop's manual. She found that the output voltage of the laptop was 19V and the output current was 7.8A.
In other words, the laptop is rated at 150W, consumes 0.15 kWh per hour.
In the USB protocol specification, USB power supply voltage is 5V , the maximum supply is 500mA. In theory, The maximum output power of a single USB port is 2.5W, power consumption is about 0.0025 kWh per hour.
Thinking of this, Avesta frowned, directly pulled out the USB, then she looked at the wiring board on the table.
This wiring board was bought by four people of this room, it is completely enough to cope with the daily life of four people.
Furthermore for convenience, what they bought specifically at that time was a wiring board with a dedicated USB jack.
Avesta looked at the USB jack marked on the wiring board. The power is 5V, 4A. In other words, the maximum power of the USB interface is 20W, and the power consumption is 0.02 kWh per hour.
Thinking of this, Avesta inserted the USB into the USB jack on the wiring board.
"If my guess is correct, if USB can use electricity to replenish energy, then it should be reflected on the electricity meter."
Avesta ponders, now the only power-consuming equipment in the dormitory is the Laptop, just close the Laptop. If the meter is still running after one hour, then it is clear that USB can indeed absorb electricity.
The reason why she didn't plug it directly into the Laptop's USB port before, It's because the Laptop's USB power is too small. The meter can only display up to two decimals. If plugged into the Laptop, even if there is energy loss, it is simply impossible to see.
Looking at the clock, Avesta took out her phone and set an alarm for one hour.
Next, she turned off the laptop, flipped out a copy of "Modern Molecular Biology" and read it quietly.
...
An hour passed quickly.
When the alarm rang, Avesta also happened to finish the book, but at this time Avesta was also not satisfied.
"Modern Molecular Biology" is not a bad book for teaching purposes, but for Avesta, it is a bit sketchy and cannot satisfy the depth of her learning.
It seemed that after this matter was finished, she would have to go to the library.
Avesta decided, then walked to the front of the electricity meter and looked at the numbers.
Available power: 52.63 kWh.
0.02 kWh was consumed in one hour, sure enough!
Avesta's eyes lit up, now he could be sure, USB can really recharge itself with electricity.
This discovery can be said to be heart-warming. Just when Avesta was excited, suddenly her ears moved slightly, and she quickly pulled out the USB and stuffed it into her pocket.
A series of footsteps approached from afar, Avesta looked towards the door, and immediately the dormitory door was opened.
Zhao Liu gently walked over.
"Avesta, why don't you go to school this afternoon!"
Seeing Avesta waiting in the dormitory, Zhao Liu immediately said, "The professor pointed out your name and specifically asked where you were!"
"I asked for leave."
Having finished speaking, Avesta collected her books, seeing that it was not yet 5:00 pm, she stood up and walked towards the outside of the dormitory.
"Where are you going, let's go out for a dinner together later?"
"No money, bye."
Avesta also didn't turn around and leave.
Her current state was clearly different from what it had been before, a point that even Avesta herself could detect.
If we say that she was once just a low-key, dull little girl, then now she is a successful person full of confidence and calmness.
No fear, no shyness,...
What she has now, is just calm and unhurried confidence.
This type of aura is very difficult to hide, so Avesta did her best to stay away from her acquaintances to avoid any loopholes being seen.
When she came to the cafeteria, Avesta bought four steamed buns for two dollars and ate two of them, then kept the remaining two steamed buns in a plastic bag, in case she was hungry at night.
People who lack money live in a simple and natural way.
And also boring.
Avesta walked towards the library, thinking about the next step.
If she wants to reach the pinnacle of life, even though Ambrosia is enough, but her greed is bottomless, how can she be satisfied with that?
The next step, of course, is to think of every possible way to supplement the USB's energy, trying to squeeze out the maximum value from the USB.
Although she didn't know how much energy the USB needed to satisfy the copying conditions, one thing was certain, it would absolutely be a huge number.
Therefore, Avesta needs a large amount of money.
Having money then, whether it's buying a factory in an industrial park, or build a power plant.
Only then can Avesta provide adequate energy for the USB, without being detected by the outside world.
So say, the source of all this is money.
Now, there is only one way for Avesta to harvest money, and that is to rely on the power of Ambrosia.
Thinking of this, Avesta no longer hesitated, both feet stepped completely into the library building.
Looking at the group of people reading books, Avesta silently sighed.
Within the next period of time, she herself will have to permanently reside here.
The library is never short of books even in the absence of people, several convenient entry and exit and quiet golden positions have all been occupied.
Avesta went to the foreign language reading room, glanced a few times, picked up a copy of "Modern College English (Second Edition)", and found a suitable place to sit down.
Once in Avesta middle school and high school, she also wondered why the Central Continent wanted to consider the North American language as a mandatory subject, and also occupied such a large proportion?
Until just now, Avesta suddenly understood.
Although she didn't want to admit it, the North American region was the true core of the Federation, whether it was economics or science and technology, it was also the true core.
And those truly profound and authoritative academic essays are mostly written in English.
There are some academic and professional words that are difficult to explain in her original language, and even if translated, the meaning is just as lacking.
Therefore, if Avesta wants to enter this field of scientific research, mastering English like this is the first move.
Just like that.
