Current Mode Interconnect - Department of Electrical Engineering
... Because of these problems with voltage mode signaling, we propose that 1’s and 0’s be signaled by the presence or absence of a current and not by a high or a low voltage. This has several advantages: • Current rise time is limited by inductance rather than capacitance. Typically, inductive effects a ...

Stray voltage
Stray voltage is the occurrence of electrical potential between two objects that ideally should not have any voltage difference between them. Small voltages often exist between two grounded objects in separate locations, due to normal current flow in the power system. Large voltages can appear on the enclosures of electrical equipment due to a fault in the electrical power system, such as a failure of insulation.
