Publisher Summary. This chapter describes different types of electrical diagrams. It explains how the diagrams are developed from original concepts into drawings that describe the full operation of the system and how further drawings, schedules, and diagrams are produced to enable the system to be constructed at the factories, installed, tested, and commissioned on site.

The non-electric telegraph was invented by Claude Chappe in His system was visual and used semaphore, a flag-based alphabet, and depended on a line of sight for communication. The optical telegraph was later replaced by the electric telegraph, which is the focus of this article.
An electrical telegraph is a telegraph that uses electrical signals, usually conveyed via telecommunication lines or electromagnetic telegraph is a device for human-to-human transmission of coded text messages.
The electrical telegraph, or more commonly just 'telegraph', superseded optical semaphore telegraph systems, such as those designed by Claude Chappe for the.
Electrical Telegraph is a device that uses electrical signals to instantaneously send and receive messages over great distances via telecommunication lines or radio. The originator of this way of communication was electromagnetic telegraph from early years of the 19th century which enabled first transfer of coded messages between vast amounts of land.
An electrical telegraph was a point-to-point text messaging system, used from the s until better systems became widespread.
It used coded pulses of electric current through dedicated wires to transmit information over long distances. It was the first electrical telecommunications system, the most widely used of a number of early messaging systems called telegraphs, devised to send text.

Conventional electric current moves from the positive surplus side of the battery (+) to the deficiency side of the battery (-) Conductors allow electrical current to easily flow because of their free electrons.
Resistors allow current to flow to some degree in proportion to their resistance in ohms. Much useful material has also been obtained from Sabine's Electric Telegraph, Culley's Hand-Book of the Electric Telegraph, Clark's Electrical Measurement, Varley's Report on the Condition of the Western Union Lines, and the columns of The Telegrapher.
