Right now, we're testing the phase shift due to an electric potential. That's amazing.

现在，我们在测试基于势的相偏移, 真是太棒了。

So now we've paused on one motor action potential that's happening right now inside of your brain.

我们现在暂停在时在你脑内的一个运动势。

Aside from solar panels, pretty much all our electricity comes from spinning turbines.

除了太阳能池板（依靠光效应产生势），大部分能都来自于驱动的涡轮。

None the less, we honor Volta's discovery today by naming our standard unit of electric potential " the volt."

尽管如，我们如今仍然把势的标准单命名为 " 伏特" ，以表彰他的贡献。

This is the reaction's electrical potential, but to its friends, it's known simply as voltage.

这是反应的势， 但对于它的朋友来说， 它被简单地称为压。

Now, the units of electric potential are Joules over Coulombs, more commonly known as Volts.

势的单是焦耳 超过库仑，称为伏特。

We’re left with an equation that describes the electric potential generated by any point charge.

我们只剩下一个描述任荷产生的势的方程式。

The graphs show the heart's OVERALL electrical potential, or voltage, as it changes over time during a cardiac cycle.

这些图形显示了心脏在一个心动周期内随时间变化的总势或压。

Now let’s put our new expressions to the test and find the electric potential difference in a real scenario.

现在让我们对新表达式进行测试， 并找出真实场景中的势差。

Now I gotta point out here that the electrical potential of a redox reaction is related to its equilibrium constant.

现在我要在这里指出， 氧化还原反应的势与其平衡常数有关。

Voltage is a measure of electrical potential energy, a type of energy related to an object's condition (and not its motion).

压是势能的量度， 是一种与物体状况（而非其运动）相关的能量。

And the electric potential difference is also called voltage, which is another way of describing a drop in electric potential.

势差也称为压。 这只是描述低延迟的另一种方式。

Now let's put our new expressions to the test and find the electric potential difference in a real scenario.

现在让我们测试一下我们的新术语， 找出现实场景中的势差。

And it works because of two main electrical principles: electric potential energy and capacitance.

它根据两个气定律运行 两个主要的：容和势能。

Now electric potential energy, which is the potential energy a charged object has due to the electric force from another charged object.

现在，势能是一个带物体由于另一个带物体的力而具有的势能。

And the electrical potential for the whole reaction, called the standard cell potential, is just the sum of the standard potentials of both half reactions.

整个反应的势称为标准池势，只是两个半反应的标准势之和。

So far, we’ve learned how to calculate electric potential for capacitors – but can we apply the same ideas to point charges?

我们已经学会了如何计算容器的势——但我们可以将相同的想法应用于荷吗？

The electric potential depends on the electric field and the position, but it does not depend on the charge of the test charge.

势取决于场 和置，并且不取决于测试货物的价值。

So far, we've learned how to calculate electric potential for capacitors – but can we apply the same ideas to point charges?

我们学会了计算容器的势，但是 我们可以将应用于积分收费吗？

And this drop in potential energy, divided by the test charge's magnitude, gives us the electric potential energy difference per unit charge, also known as the electric potential.

势能随着测试荷量的减少给我们带来了差异 单次充中的势能，又称势。
