Faraday's law : If a "conductor" is placed in a "magnetic field" the movement in either conductor or field produces an induced emf in the conductor.
In generator the produced torque will be in AC(alternating current) so commutator or slip rings is used to produce unidirectional torque required for production of Direct Current.
Basically by Faraday law the produced torque will be always bidirectional,
for alternator the bidirectional torque can be used directly.
for DC generator the unidirectional torque is needed to produce Direct Current.
A DC generator, or "dynamo", is very similar to a DC electric motor but cannot be described as "exactly the same as a motor" because a DC generator's designed purpose is not to "use" electricity (which a DC motor does) but to "make", or "produce", electricity.
Michael Faraday.
No-one 'invented' the generator as we know it, today, it simply evolved from various experiments conducted in the 19th century by scientists, such as Michael Faraday, using devices that we would not really recognise as generators these days.
An ac generator produces ac, a dc generator produces dc, it all depends on the generator.
construction of DC generator
DC
All DC machines are works based on the principle of FARADAY'S LAW OF ELECTROMAGNETIC INDUCTION.
Mike Faraday did invent the generator and motor.
The working principle is Faraday's law of electromagnetic induction. "Whenever a conductor experience the rate of change of magnetic flux an e.m.f. is induced in it",which is directly proportional to the rate of change of magnetic flux and no of conductors.
A DC generator, or "dynamo", is very similar to a DC electric motor but cannot be described as "exactly the same as a motor" because a DC generator's designed purpose is not to "use" electricity (which a DC motor does) but to "make", or "produce", electricity.
There are two types me dc generator 1 separately excited dc generator 2 self excited dc generator

I'm pretty sure it's Michael Faraday.
