RMS is a type of average. It is the "root of the mean of the squares". That is, the individual values are squared, the average is taken, and the square root of this is calculated. Since the "individual values" are often continuous - a typical example is a voltage, which continuously changes for example as a sine wave - integration must be used.

Root mean square of 6 and 24?
To find the RMS or root mean square, we first square the numbers then add the squares. So for 6 and 24 the sum of the squares is 612 Now we divide by n which is the 2 in this case so 612/2=306 and take the square root of that.=3xsquare root of 24 or about 17.4929
What is the square root of 4 and 25 multiplied?
If you mean, the square root of 4 multiplied by the square root of 5, that is 2x5=10 If you mean, the square root of ( 4x25), that is the square root of 100 which is 10
What is a principal square root?
The principal square root is the non-negative square root.
What is the third square root of 343?
If, by "third square root" you mean cube root, the answer is 7.
What is the square root of 4 times 16?
If you mean the square root of (4 x 16) the answer is 8 or -8. If you mean (the square root of 4) x 16, the answer is 32 or -32.
What did rms stand for?
RMS is root mean square in physics. RMS is Railway Mail Sevice in postal net work rms ie root mean square is got first squaring the positive and negative values to make them all positive. Then mean is taken. After that we have to take square root of the mean square. So square Root of the Mean value of the Squares of the values. Hence the name
What is a RMS?
RMS stands for Root Mean Square. It is a statistical measure of the magnitude of a varying quantity, typically used to describe the amount of power in an electrical signal. RMS is calculated by taking the square root of the arithmetic mean of the squares of the values.
What is RMS in electricity?
RMS stands for Root Mean Square. Power is calculated as V2/R where V is the voltage and R is the resistive component of a load, This is easy toi calculate for a DC voltage, but how to calculate it for a sinusoidal voltage? The answer is to take all the instantaneous voltages in the sine wave, square them, take the mean of the squares, then take the square root of the result. This is defined as the "heating effect voltage". For a sine wave, this is 0.707 of the peak voltage.
What is meant by rms velocity?
RMS velocity refers to the root mean square velocity of particles in a gas, which is the square root of the average of the squares of the velocities. It is a measure of the average speed of gas particles in a system.
Is 120vac the same as 120vrms?
No. RMS is the the true heating ability of A.C. RMS means root mean square. That is the square root of two divided by 2 equals 0.707. Multiply the A.C. times 0.707 equals RMS.
Why you need for true RMS multimeter?
RMS mean root mean square not all voltages are pure sine waves so the true RMS can be found by using this type of meter.
What does RMS stand for on motor readings?
It means root mean square. it is a notation for speed......
What is the fullform of rms?
Root Mean Square value
What is meant by rms?
rms means root mean square, or in a roundabout way the average. Therefore the average velocity or average speed (of a car?)
What is the relationship between peak current peak to peak current and RMS current?
RMS is the root mean square value.(in alternating current only)
What is the conversion for rms voltage to mean voltage?
For an alternating voltage, the simple mean over a cycle would be zero. 'RMS' means 'root mean square', and is defined as the square root of the mean value of the square of the voltage, taken over a cycle. Thus whether the voltage is + or - , as it is in alternate half cycles, the value of its square is always positive, giving a real number for the square root. In fact the RMS value of voltage produces an RMS current which dissipates power at the same rate as a DC current of the same value. To find the RMS value of a sine wave with no DC offset, divide the peak value of the sine wave by square root of 2. **************************************************** Since the r.m.s. value of a sine wave is 1.414Vpk, and the mean voltage of a sine wave is 1.57Vpk, then, starting with the r.m.s. value: Vmean = (Vr.m.s. x 1.414) ÷ 1.57
A gas consists of a mixture of neon and argon The rms speed of the neon atoms is 350 What is the rms speed of the argon atoms?
The root-mean-square (rms) speed of a gas molecule is proportional to the square root of its temperature and inversely proportional to its molar mass. Since neon and argon gases are at the same temperature, the ratio of their rms speeds will be the square root of the ratio of their molar masses. Therefore, to find the rms speed of argon atoms, you need to calculate the square root of the ratio of the molar masses of argon to neon (molar mass of argon/molar mass of neon) and multiply it by the rms speed of neon.
