Don't confuse the average magnitude Together with the RMS voltage; V a v V_ av Vav​ isn't going to equal V r m s V_ rms Vrms​. In truth, technically, the standard voltage of an unshifted sine wave is 0 V.

そんな交流電圧によって発生する電力を１周期分（波１つ分）足した時の電力が、直流電圧によって発生した電力と同じのなるとき、その電圧のことを実効値と呼んでいるのです。

BankID tilbys av bankene i Norge og er find more basert på en felles infrastruktur som er utviklet av banknæringen i felleskap.

V r m s V_ rms Vrms​ is the value indicated through anonymous the vast majority of AC voltmeters. It is the worth that, when utilized throughout a resistance, creates exactly the same amount of warmth that a direct present-day (DC) voltage of exactly the same magnitude would create.

在C语言中测量正弦波的峰峰值可以通过一些数学计算和遍历数组的方法实现。 首先，我们可以创建一个长度为N的数组来存储正弦波的采样数据，其中N是正弦波的周期内的采样点数。为了创建一个正弦波，我们可以使用循环遍历数组，并使用sin函数来计算每个采样点的值。 创建一个名为samples的数组，并使用循环遍历数组来计算正弦波的采样点值。例如，可以使用以下代码片段： ```

Copal can be a Mexican spot in Pioneer Sq. that set loads of work into producing a great Place. The food stuff needs somewhat far more of advice that hard work.

= Σxi / N，其中xi是信号或数据集中的第i个值，N是信号或数据集的总数。计算步骤：直接对数据集中的所有值进行求和，然后除以数据的个数。
