RMS Power
RMS Power determines the sound pressure level and dynamic range (including characteristic sensitivity) that a speaker system can potentially deliver in a particular room. Rated Maximum Sinusoidal. The maximum (limiting) sinusoidal power is the one at which the amplifier or speaker can operate for one hour with a real music signal without physical damage.
RMS current
The RMS current is a constant current that, during the considered time interval / in, forms in the resistor the same amount of heat as a given changing current.

The current formula is presented as I = V / R . The unit of current in the SI system is Ampere
Efficiency is often measured as the ratio of useful output to total input, which can be expressed using a mathematical formula. r \u003d P / C, where P is the number of useful products (“product”) produced for the amount C (“cost”) of consumed resources.
The formula for force, work, and time can be derived from each other as:
Power: P=W/T.
Work: W = P * T.
Time: T=W/P.
Where, P = power, W = work, T = time.
Simple: the mean value of the sine is zero. so to get the average power you calculate the square of the average voltage. Here’s what RMS stands for Root Mean Square: Take the square root of the mean (mean) squared voltage. You must take the square root to get the voltage again since you first squared it.
This is one of the reasons for using RMS voltage for AC. Because the average (average numerical value) of AC voltage is zero, it cannot be used to calculate power. Squaring a negative number gives a positive number. Finding the square root of a positive number is not a problem.
Direct current is not used in households because for the same voltage value, direct current is more dangerous than alternating current since direct current does not pass through zero. Electrolytic corrosion is more of a DC problem. DC inductors are more complex. This requires commutators, electronic switches, and brushes.
