Electrostatic machines are typically used in science classrooms to safely demonstrate electrical forces and high voltage phenomena. The elevated potential differences achieved have been also used for a variety of practical applications, such as operating X-ray tubes, particle accelerators, spectroscopy, medical applications, sterilization of food, and nuclear physics experiments.
At that time, the word "battery" was a military term for a group of cannons. [32] Franklin was the first to apply the terms "positive" and "negative" to electricity. Through his research, Franklin was among first to prove the electrical principal of conservation of charge in 1747: [ 16 ] [ 24 ] a similar discovery was made independently in 1746 ...

Condition monitoring techniques are normally used on rotating equipment, auxiliary systems and other machinery like belt-driven equipment, (compressors, pumps, electric motors, internal combustion engines, presses), while periodic inspection using non-destructive testing (NDT) techniques and fit for service (FFS) [1] evaluation are used for ...

The notion of a symbol for an ESD protection device came about in response to the increased usage and failures of static sensitive components by then the computer systems manufacturer, Sperry Univac. Field repairs to and handling of ESD printed circuit boards (PCBs) were resulting in extremely high failure rates. Studies of PCB failures ...
Ruggedized infrared equipment used by some firefighters to detect hidden people, animals, heat sources (i.e., fire) and structural compromise. Tones A series of two or three musical notes, used as an auditory alert over a radio or radio-paging system to indicate that a particular fire company, district, or territory is dispatched to service on ...
