Cigarette smokers who craved a cigarette were given a single 20-minute treatment of CES consisting of 0.500-500 microamperes of current, 0.5 Hz frequency, using earclip electrodes in a medical practice.

For example, the first generation of solid-state batteries, which only produce around 0.7 microamperes, are used to power radio-frequency identification tags.
At a certain value of the electric field strength into which the lightning detector is placed, streamer flashes with a current of tens of mA occur against the background of a <<quiet>> corona whose current is not more than hundreds of microamperes. Only a streamer flash can transform into a leader under certain conditions.
Voll determined from school children the approximate skin conductance in the healthy state, that being around 1.25 volts at fifty microamperes. Were the human body in a perfect state of health, no points on the skin surface would be 'active', that is, exhibit a deviation from this measurement of the normotonic state, just as no deviation is found on a lie detector when a person speaks the "truth." That actually is a blessing, meaning only active points are detectable and remarkable, which certainly narrows down the field of inspection to a least amount of points and surface zones required for evaluation.
Given the 90 mAh estimated capacity of the battery, a 6-month battery life requirement, and a cut-off voltage of 2.4 volts (due to the temperature sensor used), the maximum allowable current consumption of the device is 19 microamperes.
Limits of stimulation parameters (in microamperes) of nondisabled subjects.
This approach eliminates the need for a direct superposition of large AC and low DC voltage sources, it preserves isolation between primary and secondary circuits and finally, DC current that is injected through the secondary side has to be in mA range in contrast with primary range of microamperes, which is more critical for the maintenance.

As laminas ficaram nessa solucao por 20 minutos em repouso para permitir o desenovelamento do DNA, posteriormente foi realizada a eletroforese por 20 minutos a 25 Voltz (V) e 300 microAmperes (mA).
SQUIDs operate with one magnetic flux state corresponding to a few microamperes of current flowing clockwise and the other corresponding to the same amount of current flowing anticlockwise, so they can be in two states simultaneously.
