The RMS value of a set of values (or a continuous-time waveform) is the square root of the arithmetic mean of the squares of the values, or the square of the function that defines the continuous waveform. In physics, the RMS current value can also be defined as the "value of the direct current that dissipates the … See more In mathematics and its applications, the root mean square of a set of numbers $${\displaystyle x_{i}}$$ (abbreviated as RMS, RMS or rms and denoted in formulas as either $${\displaystyle x_{\mathrm {RMS} }}$$ See more In electrical engineering Voltage A special case of RMS of waveform combinations is: See more If $${\displaystyle {\bar {x}}}$$ is the arithmetic mean and $${\displaystyle \sigma _{x}}$$ is the standard deviation of a population or a waveform, then: From this it is clear that the RMS value is always greater than … See more The RMS can be computed in the frequency domain, using Parseval's theorem.

Accordingly, find the effective (RMS) value using the piecewise function of the welding current and calculate the average (active) power consumed on the resistor R.
WebDefinition and Evaluating Piecewise Functions. A piecewise function is a function defined separately for different intervals of – values (different domains). The simplest example to illustrate this is the absolute value function, defined by: This means that: when is less than. when is greater than or equal to.
