What is the definition of rms?
Asked by mks_619 | 27 Jun, 2011, 02:49: PM
answered-by-expert Expert Answer
rms stands for root mean square quantity. For example rms speed of the atoms or molecules of a gas defined as the square root of mean square of speeds of individual atom or molecule.
 
vrms = sqrt {(v12 + v22 + v32 +.......vn2)/n}
