Average Value of an Alternating Current (AC)
Definition, Formula
The average value of an alternating current is defined as the DC current which transfers across any circuit the same charge is transfers by that alternating current during the same time.
AVERAGE
VALUE
The
average value of an alternating current is defined as the DC current which
transfers across any circuit the same charge is transfers by that alternating
current during the same time.
In
case of symmetrical waveforms the average value taken over the complete cycle
is zero. (Ex) sinusoidal waveform.
In
case of unsymmetrical waveforms the average value must be taken for whole
cycle. (Ex) Half wave rectified waveform.
If
the time period is divided into a number of equal intervals N, then the current
at each interval of time is given by i1,i2,.... iN
and the average value is
for symmetrical
for unsymmetrical
