Such a motor can produce a transient overvoltage, reaching many thousands of volts, when the normal rms current is interrupted.

当通常的均方根电流被打断，这样的一个电机可以产生一个可达几千伏的电涌过压。

Ceramic capacitors are often chosen because of their small size, low equivalent series resistance (ESR) and high RMS current capability.

陶瓷电容因其体积小、等效串联电阻小和具有较大的RMS电流而常被人们采用。

By comparing the heating effect of an unknown AC signal to that from a known DC reference, metrologists can determine the RMS AC quantity (voltage or current) in terms of the DC quantity.

为了对比一个已知直流参考的未知交流信号热效应，计量人员可以确定在一段时间内直流的交流有效值(电压或电流)。

Fret not, though, as the company assured us it'll be using tiny class-D digital amping that won't affect its current size, aiming to provide 80-100 peak RMS watts of power.
