RMS value is the amount of heat produced by a resistor when at a time both AC and DC are passed through it. Average value is the area of the one cycle of sinusoidal wave to the time period. However, instantaneous value is the value at a particular instant. Let us further understand these concepts below.
Why is RMS better than average?
Average is used to get the central tendency of a given data set while RMS is used when random variables given in the data are negative and positive such as sinusoids.
Is RMS equal to average?
so to get average power you calculate average voltage squared. That's what the RMS refers to: Root Mean Square: take the square root of the average (mean) of the squared voltage. You have to take the square root to get the dimension of a voltage again, since you first squared it.
Which is greater RMS or average?
It shows that Vrms is greatest and Vmp have least value. So RMS velocity> average velocity > most probable velocity. Hence, the correct option Is (A).
