Difference between RMS current and RMS emf
The RMS stands for root mean square . In very simple words RMS is if we have a current at different interval of time then simply take addition of each positive value and divide it by number of sample we have so we get the mean square and after taking its square root we will get the root mean square. RMS current is defined as the value of steady current which would generate the same amount of heat as it generated by alternating current in the same circuit for the full time period. In other words RMS or root mean square current represents the d.c. current which dissipates the same amount of power as the average power dissipated by the alternating current. The root mean square electro motive force is defined as that value of steady emf which would genrate the same amount of heat as it is genreted by alternating emf in the same circuit for full time period. The root mean square electro motive force voltage of a sinusoidal source is used to characterize the source. The difference between RMS current and RMS EMF is as follows
RMS Current | RMS EMF |
1) RMS current is defined as the value of steady current which would generate the same amount of heat as it generated by alternating current in the same circuit for the full time period.
2) RMS current is used to find the effective value of the current. 3) The RMS current is given by Irms = I0 / √2 = 0.707 I0 |
