I have of late purchased a number of multimeters and they all read the same value under normal usage circumstances however when used in a way that is not normal they all give different values, some giving none others not.
For example i have a non self calibrating digital meter which when used to measure the voltage between each hand shows around .4V. On an analogue meter i have it shows nothing.
What i assume is happening here is the digital meter is measuring the degree of polarization which equates to the amount of voltage. Because the analogue meter directly converts the voltage into mechanical action it results in no change on the meter.
What is interesting is that you can polarize something cheaply and when coupled with real charge results in an increase in power after you just increased the voltage for cents and how much you increase it by does not effect the switching cost. Unfortunatly when we charge a capacitor the charge and voltage/polarization are coupled together and is very difficult to seperate them without using weird geometry.
In something like the human body the polarization/potential is spatially distributed
Has anyone else noticed similar things.
