Balanced, differential serial connections such as RS-422, RS-485, and USB can tolerate larger ground voltage differences because of the differential signaling.
32.
Most often the spark gaps generator where a strong voltage difference between two pieces of metal generates small bolts of lightning.
33.
Sections of the borehole where this occurs then have a voltage difference with other nonpermeable sections where ion movement is restricted.
34.
A large voltage difference gradually creates a conductive leakage path across the surface of the material by forming a carbonized track.
35.
A segment required to be " off " has an in-phase squarewave applied to it-it thus has zero voltage difference across it.
36.
The ADC outputs a number with a fixed step size, each step representing a voltage difference of, in this case, 0.2 pounds.
37.
A low resistance connection, such as a wire jumper from ground to neutral can carry very high current from this small voltage difference.
38.
The EM tool generates voltage differences between the drillstring sections in the pattern of very low frequency ( 2 12 Hz ) waves.
39.
:: If you disconnect the data bus between the two boards, is there a voltage difference between the grounds of the two boards?
40.
If there is even a little permeability to water, ions can move through the rock and decrease the voltage difference with the mud nearby.
