Origin Of Capacitors
Dec 21, 2018

Leiden bottles were invented by the Dutch physicist masenbrock (1696-1761) between 1745 and 1746. Masenbrock was born in Leiden, Holland, hence the name Leiden bottle. The "bottle" was a capacitor. At that time, this phenomenon often happened, that the electricity which was hard to get was gradually disappearing in the air. To find a way to conserve electricity, massenbrock tried to store it in water bottles. He suspended an iron rod in the air with two wires and connected it with a motor. He asked one of his assistants to hold the glass bottle with one hand. Massenbrock was beside him shaking the motor vigorously. At this moment, his assistant accidentally touched the iron bar with the other hand. There was a shiver all over his body, and masenbrock changed hands with his assistant, who shook the motor. He held the water bottle in his right hand and touched the iron bar with his other hand. He came to the conclusion that electricity could be saved by placing a charged body in a glass bottle. It was just not clear at the time whether it was the bottle or the water in the bottle that was responsible for storing the charge, as it is now called.

Before long, Leiden bottles were modified to cover both the inner and outer walls with foil. A metal bar is inserted into the top cover of the leighton bottle. Its upper end is connected to a metal ball, and its lower end is connected to the inner wall through a metal chain. So the leyton bottle is actually a normal capacitor. If the outer wall is grounded and the metal ball is connected to the charge source, a considerable amount of charge will accumulate between the inner and outer walls of the leighton bottle. The leyton flask can be discharged with a considerable current.

The invention of leighton bottle provided an effective method for the scientific community to store electricity, provided a new and powerful means for further in-depth study of electrical phenomena, and played an important role in the dissemination and development of electrical knowledge. In the same year that the Leiden bottle was invented, a British physicist named corrinson sent letters to Benjamin Franklin (B. Fanklin, 1706-1790) mailed a lytton bottle and explained how to use it in the letter, so that the knowledge of the electricity brought by the leyton bottle soon spread to North America. Franklin was very interested in this, and made a series of experiments with Leiden bottles, and made an in-depth analysis of the effects of Leiden bottles.
