Im = 2 x Ip / π = circa 0,63 Ip
For a rectangular faradic current it can be calculated through the formula:
Im = I x t x f / 1000
where: Im is the mean current in mA
I is the pick current of the rectangular faradic impulse in mA
t is the time of impulse in millisecond
f is the frequency of repetition in Hz
Naturally if the emission of impulses is not carried out continuously but interrupted by pauses, we have to think about the
multiplicative factor:
A / (A+P)
where: A is the time of action in seconds
P is the time of pause in seconds
For example for a faradic current of 30 mA applied continuously to the frequency of 100 Hz, with impulses of 1 msec we
obtain:
Im = 30 x 1 x 100 / 1000 = 3 mA
If the time of action is: A = 3 seconds
And the time of pause: P= 6 seconds
The multiplicative factor will be:
A / (A+P) = 3 / (3+6) = 1/3
And so the mean current will be:
Im / 3 = 1 mA
For a triangular current it can be calculated through the formula:
Im = I x t x f / 2000
where: Im is the mean current in mA
I is the pick current of the triangular impulse in mA
t is the time of impulse in milliseconds
f is the frequency of repetition in Hz
