A.C CIRCUITS – MODULE 2
STANDARD EQUATION OF AN ALTERNATING VOLTAGE
ROOT MEAN SQUARE (R.M.S) VALUE
# FOR SINUSOIDAL SYMMETRICAL WAVES (SINUSOIDAL)
FINDING R.M.S VALUE USING MID-ORDINATE METHOD
,FINDING R.M.S VALUE USING ANALYTICAL METHOD
# FOR COMPLEX WAVES (FOR NON-SINUSOIDAL WAVES)
METHOD 1:
METHOD 2
If the equation of the wave is known then Irms or Vrms is given by
, AVERAGE VALUE
# FOR SYMMETRICAL SINUSOIDAL WAVES
Average value over a complete cycle = 0
Average value is always taken for a half cycle in this case
# FOR COMPLEX WAVES (NON-SINUSOIDAL)
