Using an Oscilloscope to Observe Rectification
... An oscilloscope is a measurement instrument that displays a picture of the way that a voltage changes over a period of time – i.e. it draws a graph that plots voltage (vertically) against time (horizontally). The oscilloscope display screen is divided into 1 cm squares. The controls on the oscillosc ...

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.
