... Sure-Lites’ line-latched electronic circuitry makes installation easy and economical. A labor efficient AC-activated load switch prevents the lamps from turning on during installation to a non-energized AC circuit. Line-latching eliminates the need for a contractor’s return to a job site to connect ...

Experiment 8
... In the circuit shown in Figure 8-4 above, the source voltage, Vs, is “chopped” to produce an average voltage somewhere between 0% and 100% of Vs. Thus the average value of the voltage applied to the Load, VL, is controlled by closing and opening the “switch”, Q1. To close the switch, a firing signal ...

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.
