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 ...

A short metal chain hangs from the central bell. The system of operation of the Franklin clock considers that the electrostatic force generated by an electric field is used to move the pendulums that strike two metal bells. [8] [9] The Franklin bells uses a metal rod as a lightning rod to attract current. One bell is connected to the lightning ...
The Leyden jar was used to conduct many early experiments in electricity, and its discovery was of fundamental importance in the study of electrostatics. It was the first means of accumulating and preserving electric charge in large quantities that could be discharged at the experimenter's will, thus overcoming a significant limit to early ...
For children in the age range 10−13, batteries are used to illustrate the connection between chemistry and electricity as well as to deepen the circuit concept for electricity. The fact that different chemical elements such as copper and zinc are used can be placed in the larger context that the elements do not disappear or break down when ...
Between 1747 and 1750, Franklin sent many letters to his friend Collinson in London about his experiments with the electrostatic machine and the Leyden jar, including his observations and theories on the principles of electricity. [12] These letters were collected and published in 1751 in a book entitled Experiments and Observations on Electricity.

He also suggested that electricity is more akin to magnetism and light than to a fluid, since it passes through glass and cloth, and can be concentrated as a spark to light up flammable materials. On 14 August 1747 he made an experiment to conduct electricity through a 6,732 foot long wire at Shooter's Hill in London. At another experiment he ...
