LED's require resistors to control current when used with batteries rated at over 2 volts.
当使用2伏以上的电池时,需要使用额外的电阻来帮助控制电流。
In the case of lead and lead dioxide, this potential difference is just over two volts per cell.
以铅和二氧化铅为例的电池,每节电池的电位差可产生2伏电压。
Electrical Circuitry: Converters stabilize the current's varying frequencies. Transformers boost voltage from 690 volts to more than 22,000, so current travels efficiently over long-distance lines.
电气线路:利用整流装置稳定电流的变化频率,此外通过变压器把690伏特的电压提升到超过2200 0伏特,大大提高了电流长途输送的效率。
This will be 13.6 over 100 electron volts.
这相当于13。6倍的100电子伏特。
