Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it can move away by an electric current or electrical discharge . The word "static" is used to differentiate it from current electricity , where an electric charge flows through an electrical conductor .
By rubbing a balloon or other object to create a static charge, and then using the charge to activate the bells, students can see the effects of static electricity and learn how it can be harnessed and utilized. [5] The Franklin Bell is now a common electrical experiment demonstration in high school and introductory college physics courses.
In its day, it was the most powerful way of generating static electricity and was remarkable for having no moving parts. [2] At a demonstration at Newcastle's Lit and Phil, the crowds were so great that Armstrong could not gain entry through the door and had to climb in through a window, this requiring two ladders.
Small Van de Graaff generators are commonly used in science museums and science education to demonstrate the principles of static electricity. A popular demonstration is to have a person touch the high voltage terminal while standing on an insulated support; the high voltage charges the person's hair, causing the strands to stand out from the head.
Several 18th-century electric terms were derived from his name. For example, static electricity was known as "Franklin current", [37] and "Franklinization" is a form of electrotherapy where Franklin shocked patients with strong static charges, to treat patients with various illnesses. [38] [39]
Benjamin Franklin Drawing Electricity from the Sky, an artistic rendition of Franklin's kite experiment painted by Benjamin West, c. 1816 The BEP engraved the vignette Franklin and Electricity (c. 1860) which was used on the $10 National Bank Note from the 1860s to 1890s.
A metal object C (Faraday used a brass ball suspended by a nonconductive silk thread, [1] but modern experiments often use a small metal ball or disk mounted on an insulating handle [4]) is charged with electricity using an electrostatic machine and lowered into the container A without touching it. As it is lowered the charge detector's reading ...
The Elekiter relied on the various Western experiments with static electricity during the 18th century, which depended on the discovery that electricity could be generated through friction, and on the invention of the Leyden jar in the 1740s, as a convenient means to store static electricity in rather large quantities.
