As the name implies, Vrms is calculated by taking the square root of the mean average of the square of the voltage in an appropriately chosen interval. In the case of symmetrical waveforms like the triangle wave, a quarter cycle faithfully represents all four quarter cycles of the waveform.Just so, why is RMS used?
Attempts to find an average value of AC would directly provide you the answer zero Hence, RMS values are used. They help to find the effective value of AC (voltage or current). This RMS is a mathematical quantity (used in many math fields) used to compare both alternating and direct currents (or voltage).
Beside above, what is RMS power? Mean power, or root mean square (RMS) power handling, refers to how much continuous power the speaker can handle. For example, a speaker with a 30W RMS rating but a peak rating of 60W means that speaker can comfortably run with 30 watts of continuous power, with occasional bursts of up to 60W.
Also, what does RMS stand for?

What is RMS current?
In physics, the RMS current value can also be defined as the "value of the direct current that dissipates the same power in a resistor." In the case of a set of n values , the RMS is. The corresponding formula for a continuous function (or waveform) f(t) defined over the interval is.
What is RMS value of AC?
RMS Value of Alternating Current RMS stands for root mean square of instantaneous current values. The RMS value of alternating current is given by direct current which flows through a resistance. The RMS value of AC is greater than the average value. It is denoted by Irms or Iv.What is rms value and average value?
If a wave is represented by a RMS value then it is the closest possible DC value of that wave. So RMS value is defined as the square root of means of squares of instantaneous values. Whereas an average value just considers the sum of all instantaneous values ( positive and negative).What does Vrms mean?
alternating current In electricity: Alternating-current circuits. The root-mean-square (rms) voltage of a sinusoidal source of electromotive force (Vrms) is used to characterize the source. It is the square root of the time average of the voltage squared. The value of Vrms is V0/ √2, or, equivalently, 0.707V0.What is average value of sine wave?
The average value of a whole sinusoidal waveform over one complete cycle is zero as the two halves cancel each other out, so the average value is taken over half a cycle. The average value of a sine wave of voltage or current is 0.637 times the peak value, (Vp or Ip.What is peak value?
Peak Value. Definition: The maximum value attained by an alternating quantity during one cycle is called its Peak value. It is also known as the maximum value or amplitude or crest value.What is peak voltage?
Peak voltage is the highest point or highest value of voltage for any voltage waveform. It is a power quality issue that occurs when devices that use Pulse Width Modulation, such as a variable frequency drive, is added to a power system.
