The Root Mean Square(R.M.S) value of an alternate current supply converts the electrical energy to thermal energy at an equal rate in a given resistance and the R.M.S. value is also called as effective value denoted by Irms, Ieff or Ii.
I = Current
In a radio circuit, the a.c voltage across a resistor is given by v=8sin120.Calculate the RMS Alternate Current of the radio circuit.
I = 80sin200
Root Mean Square Alternate Current
I = 80sin200 I = 80 * 0.873297297 I = 69.8378376 Substitute the given values in the formula,
|RMS Alternate Current Irms||= I / √2|
|= 69.8378376 / 1.414213562|
