Telegraph
A telegraph is an instrument that transmits messages over long distances by sending electrical signals through wires. This technology revolutionized communication in the 19th century by enabling people to send messages more quickly than traditional means like mail.

The telegraph was much faster than horseback messaging, as it could send messages instantly over long distances at the speed of electricity. This was a significant improvement over the time it took for messages to be delivered by horseback, which could take days or even weeks depending on the distance.
When electricity is transmitted over long distances, it can experience energy losses in the form of heat due to resistance in the transmission lines. This can lead to a decrease in voltage levels, which may require additional equipment such as transformers to boost the voltage back up along the way. Additionally, environmental factors like temperature and weather conditions can also affect the efficiency of electricity transmission over long distances.
The telegraph was the machine that sent messages along wires using electricity. Developed in the early 19th century, it used a system of electrical signals to transmit messages over long distances through coded pulses, typically represented by Morse code. This innovation revolutionized communication, enabling near-instantaneous exchange of information compared to previous methods.
High voltage transmission lines use electricity to efficiently transport power over long distances by increasing the voltage of the electricity. This allows for the power to travel long distances with minimal loss of energy. The high voltage reduces the amount of current needed, which in turn reduces the energy lost as heat during transmission.
Electricity produced at a generating station is typically alternating current (AC) electricity. This type of electricity is used for transmitting power over long distances and is the form of electricity supplied to homes and businesses.
When electricity is transported long distances via large overhead transmission lines, the voltage can be transformed up to 500,000 volts (B). This high voltage reduces energy loss during transmission, allowing for efficient delivery of electricity over long distances.
