So we shorten this to say that the ideal voltage supplied by the battery is its emf.

所以我们缩小范围，说理想电压 由电池提供的是它的电动势。

So their voltage drops will still affect how much voltage the circuit can supply to other components that DO need to dissipate power.

因此，它们的电压降仍然会影响电路可以为其他需要耗散功率的组件提供多少电压。

According to the conservation of energy, the total voltage supplied to the system is equal to the sum of all the voltage drops across the circuit.

根据能量守恒，提供给系统的总电压等于电路上所有电压降的总和。

By flipping the switch, you've either started or ended a voltage supply, but an inductor in the system delays the current from starting or stopping immediately.

通过拨动开关，您可以启动或终止电压供应，但系统中的电感器会延迟电流立即启动或停止。

If the voltage supplied by a battery is the equal to the sum of all voltage drops across, say, three resistors in a series, you can substitute Ohm’s law for each resistor.

如果电池提供的电压等于所有电压降的总和， 例如串联的三个电阻器， 您可以用欧姆定律代替每个电阻器。

If the voltage supplied by a battery is the equal to the sum of all voltage drops across, say, three resistors in a series, you can substitute Ohm's law for each resistor.

如果电池提供的电压等于串联的三个电阻器上的所有电压降之和，则可以用欧姆定律代替任何电阻器。

That comes out to a voltage drop of 15 Volts, which makes sense, because then the sum of each drop in the loop is equal to the voltage supplied by the battery.

结果是 15 伏的电压降，这是有道理的，因为回路中每个电压降的总和等于电池提供的电压。
