The spark consists of an electric are produced by applying a high voltage across the electrodes of a spark plug.

火花由电弧产生，是由经过火花塞电极的高电压形成的。

This spark is provided by a high-voltage electrical surge jumping across the gap of the spark plug that is ideally positioned in the combustion chamber.

火花是由一个高电压的电涌跳过火花塞间隙而产生的，火花塞是恰当地安装在燃烧室中的。

When I travel, I carry both a voltage and a plug adapter.

FORBES: Standardization: Important Lessons for the Cloud

Once, before dual voltage became the standard for consumer electronics, there was plentiful physical evidence of the fact that if you plug in across systems without a transformer, the result is either a flame-out or a non-starter.
