How are electrical signals transmitted over long distances?

Answer: Electric Signals Are Transmitted Over Long Distances By Neurons

Explanation: Neurons transmit signals long distances using a different type of electrical change, called action potentials. Action potentials produce much larger changes in membrane voltage. They can also be regenerated at regular intervals, allowing neurons to transmit signals quickly over long distances

Over such small distances, digital data may be transmitted as direct, two-level electrical signals over simple copper conductors. This results from the electrical distortion of signals traveling through long conductors, and from noise added to the signal as it propagates through a transmission medium.
