Bit rate is the number of bits transmitted during one second whereas baud rate refers to the number of signal units per second that are required to represent those bits.
baud rate = bit rate / N
where N is no-of-bits represented by each signal shift.
Michael Faraday invented Electric Generator in 1831.
The operating principle of electromagnetic generators was discovered in the years of 1831–1832 by Michael Faraday.
The principle later called Faraday's law, is that an electromotive force is generated in an electrical conductor which encircles a varying magnetic flux.
