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。

PL3223 supplies several indirect parameters, which are used to calculate voltage RMS, current RMS, frequency of the line voltage and so on.

PL 3223提供若干间接参数，依此计算出电压有效值、电流有效值、线电压频率等参量。

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.
