How did the initial telephone transmission differ electrically from the Morse Telegraph transmission?

Answer

The telephone used continuous electrical current mirroring sound waves, while the telegraph used coded electrical pulses.

The fundamental shift was from the telegraph's coded dots and dashes to the telephone's ability to transmit the continuous electrical variations corresponding to the vibrations of sound waves.
