Around 1650, Otto von Guericke built a crude friction generator? - a sulphur ball that rotated at high speed on a shaft. When Guericke held his hand against the ball and turned the shaft quickly, a [static charge]? built up. In 1745, another German, Ewald Georg von Kleist, found a method of storing this charge. He lined a glass jar with silver foil, and charged the foil with a friction machine. Kleist was convinced that a substantial charge could be collected when he received a significant shock from the device. |
The Leyden Jar is the original capacitor. Around 1650, Otto von Guericke built a crude friction generator? - a sulphur ball that rotated at high speed on a shaft. When Guericke held his hand against the ball and turned the shaft quickly, a [static charge]? built up. In 1745, another German, Ewald Georg von Kleist, found a method of storing this charge. He lined a glass jar with silver foil, and charged the foil with a friction machine. Kleist was convinced that a substantial charge could be collected when he received a significant shock from the device. In 1746, Pieter van Musschenbroek of Leyden?, Netherlands, independently made the same discovery. The device is known as a "Leyden jar" because Musschenbroek made the storage jar known to the scientific world. |
About a year later, Pieter van Musschenbroek of Leyden?, Germany, independently made the same discovery. The device is known as a "Leyden jar" because Musschenbroek made the storage jar known to the scientific world. |
