DC, or Direct Current, was not invented in the traditional sense as it is a very simple and common way to transfer power through a conductor. Far too common to pinpoint the first person who discovered it. Thomas Edison developed direct current, but it was only with Nikola Tesla's help that Edison ever developed any useful generators for direct current. It's odd that we credit Edison with inventing the light bulb AND direct current when Nikola Tesla is to direct current what Edison is to the light bulb.
An ac generator produces ac, a dc generator produces dc, it all depends on the generator.
construction of DC generator
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.
It may not be possible to physically convert AC generator to DC generator. What can be done is that 'Rectifier' of suitable capacity can be connected to the out put of AC generator to get DC supply.
demagnetising effect of dc generator is to reduce main field flux there by reduction in generated voltage.
first dc generator is max generator donno who invented t
AC/DC-Tesla/EdisonEdison's DC was the first person who came up with the generator and.He made it.
There are two types me dc generator 1 separately excited dc generator 2 self excited dc generator
An ac generator produces ac, a dc generator produces dc, it all depends on the generator.
A DC generator is a DC machine that is driven by an external rotating force. It is constructed the same as a DC motor.
By the operation supply 1.AC generator 2.DC generator In DC generator we are having the following types according to the construction 1.DC Series Generator 2.DC shunt Generator 3.DC Compound Generator
what is necessity of commutator in DC generator
Turn the DC generator inside out and you have an alternator .
construction of DC generator

DC generator is used to produce direct current. The basic DC generator have four basic parts 1. A magnetic field 2. A single conductor or loop 3. A commutator 4. Brushes
