When did China start using telegraphs?

The earliest use of electric energy in China was in the fifth year of Guangxu in the Qing Dynasty (1878).

The British colonialists in Shanghai at that time brought a small engine generator to welcome the American ** Grand Grande passing through Shanghai, which was used for two nights on the Bund in Shanghai from August 17 to 18, 1879. On July 26, 1882, the Zhapu Road Electric Light Factory, which belonged to the Shanghai Dianguang Company opened by British businessmen, began to generate electricity, which was the first power plant to officially generate electricity on the land of China. Six years after the power plant was generated, Jinjing began to run electricity, and it was the first to use electricity in North China.

Electricity has been in use since 1979 and is a natural phenomenon that refers to the physical phenomenon created by a stationary or moving electric charge, a property of the repulsive force and attraction that arises between subatomic particles like electrons and protons. Lightning in nature is an electrical phenomenon. The electromagnetic force is one of the four fundamental interactions in nature.

There are two phenomena of electron motion: we say that an atom that lacks electrons is positively charged, and an atom that has excess electrons is said to be negatively charged. Electricity is a physical phenomenon produced by a stationary or moving electric charge.

In real life, the mechanism of electricity gives many well-known effects, such as lightning, triboelectric induction, electrostatic induction, electromagnetic induction, etc.

There was electricity in the last years of the Qing Dynasty

1. The earliest use of electric energy in China was in the fifth year of Guangxu in the Qing Dynasty (1878), when the British colonialists in Shanghai in order to welcome the American ** Grand Passage through Shanghai, specially transported a small engine generator, from August 17 to 18 in the fifth year of Guangxu in the Qing Dynasty (1879) on the Bund in Shanghai for two nights to dismantle the balance.

2. The earliest power plant in China was the Shanghai Dianguang Company, which was established by the British in the Shanghai Concession in 1882.

History of electricity

1. In ancient times, people discovered its existence through 'lightning'.

2. In ancient China, the ancients believed that the phenomenon of electricity was caused by the stimulation of yin and yang.

3. Regarding static electricity, when amber or tortoiseshell is rubbed, it can attract light and small objects, and it also describes the phenomenon of electricity caused by silk friction.

4. In 1600 AD, the English doctor Gilbert did many years of experiments and discovered many phenomena such as "electricity" and "electric attraction", and was the first to use special terms such as "electricity" and "electric attraction", so many people call him the father of electrical research.

Franklin, a great American electrician, flew a kite experiment, further revealing the nature of electricity and proposing the term electric current.

Faraday, an Englishman, made a major invention of electricity.

German Siemens built the world's first industrial generator.

The telegraph was first invented by Morse in the United States in 1844, so it is also called Morse code. It consists of two basic signals and different intervals: short dot signals"．"read (di); Hold a long signal for a certain period of time"—"Read (da).

Morse code, also known as Morse code, is a signal** that is arranged in different order to express different letters, numbers, and punctuation marks. It was invented in 1837 and was an early form of digital communication. Unlike modern digital communication, Morse code uses only zero and binary in one or two states, and it includes five types

Short dot signal "·" The long signal "—" that is held for a certain amount of time indicates a pause between dots and strokes, a medium pause between each word, and a long pause between sentences.

The telegraph originated in the United States.

Although the development of the telegraph began as early as the beginning of the 19th century, the invention of the practical electromagnetic telegraph was mainly attributed to the British scientists John Cook and Wheatstone and the American scientist Morse.

In 1836, John Cook made an electromagnetic telegraph and applied for the first telegraph patent the following year. Wheatstone was a collaborator of John Cook.

Today's telegram

With the development of communication technology, the telegraph is no longer the main method of communication. Since the digitization of the network, telegraph communication has become one of the applications of text communication in the digital communication network, and it has been replaced by fax after the popularization of fax machines. With the increasing use of the Internet and mobile communications, the telegraph was further replaced by e-mail and text messages.

The average person no longer uses telegraph communication. Traditional telegraph news (i.e. telecommunication press releases) has also been replaced by fax, Internet and handheld** SMS. It is only in some very special old application environments that you will stumble upon telegraph services using teletypewriters.

Developed in Britain and the United States in the thirties of the 19th century, the telegraph was one of the first reliable means of instantaneous long-distance communication to transmit information through electricity.

The first telegraph line in operation was first introduced in England in 1839. It was installed on the Great Western Railway for communication between two stations. The 13-mile long line is an analogue design invented by Charles Wheatstone and William Cook.

The two obtained a British patent for their invention in 1837.

In the United States, Samuel Morse invented the telegraph at about the same time and patented it in the United States in 1837. Morse also developed a method of encoding letters and numbers for photographic purposes, known as Morse code.
