In 2018 Epic launched a PC games store, charging a 12% commission.

2018年，Epic推出了一款电脑端游戏商店，收取12%的佣金。

So why does this happen, and how do our batteries even store so much charge in the first place?

这为什么会发生呢？还有我们的电池最初是如何存放如此多电荷的呢？

Those electrodes store an electric charge.

这些电极存储电荷。

These screens are called capacitive touchscreens because the nodes act like capacitors by storing charge.

这些屏幕被称为电容式触摸屏，因为节点通过存储电荷就像电容器一样。

When a capacitor's plates store electric charge, they're actually storing energy!

当电容器板存储电荷时，它是 事实上，它储存能量！

Among the most promising, though, are water-based batteries inspired by the way an electric eel stores its charge.

最有前景的之一是受电鳗储存电荷方式启发的水基电池。

In a DC circuit, a capacitor is useful for storing charge temporarily, then releasing it again later on.

在直流电路中，电容器可用于暂时存储电荷，然后再将其释放。

When you touch this artificial skin, it’s compressed: meaning that the rubber thins, and is able to store less electrical charge.

当你触摸这种人造皮肤时，它会被压缩：这意味着橡胶会变薄，并且能够储存更少的电荷。

Sometimes, as the plates get hotter or the voltage gets higher, some electrons naturally jump between the plates, decreasing the amount of stored charge.

有时，当极板升温或张力升高时，电子会跳跃 自然地在板之间，减少存储的电荷量。

More humidity means more water molecules, which means a greater ability to store an electrical charge, which also can be detected by sensors.

更多的湿度意味着更多的水分子，这意味着更大的存储电荷的能力， 这也可以被传感器检测到。

From our earlier lessons, you know that the amount of charge stored in a capacitor is equal to the voltage across the capacitor times its capacitance.

从我们之前的课程中，您知道存储在电容器中的电荷量等于电容器两端的电压乘以其电容。

Because it’s largely why capacitors are so incredibly useful – from defibrillators to electronic components: When a capacitor’s plates store electric charge, they’re actually storing energy!

因为这在很大程度上是电容器如此有用的原因——从除颤器到电子元件：当电容器的极板储存电荷时，它们实际上是在储存能量！

But one team now reports in Buildings that it has developed a rechargeable prototype that could represent a more than 900 percent increase in stored charge, compared with earlier attempts.

但是一个团队现在在 Buildings 中报告说， 它已经开发出一种可充电原型，与之前的尝试相比， 它可以代表存储电量增加 900% 以上。

This pair of plates is known as a capactior and is an integral part of almost every electronic system partly because it can use its electronic field to store an electric charge.

这对极板被称为电容器，它是一个集成部分 在几乎所有电子系统中。
