because the dc motor will act as dc generator as same as dc generator acts as a dc motor .so it is called as dc machines.AnswerBecause generators and motors are machines, and operate on d.c.'A.C. machines' are generators, transformers, and motors which operate on a.c.
i don't know......sorry =)
A Rectifier converts Alternating current into Direct current
Currently Polaris is the best brand on DC generators. Hitachi and Coleman also make very reliable ones.
on the basis of field excitation, dc generators are classified into the following types:-1- separetly excited dc generators2-self excited dc generatorsthe behaviour of a dc generator on load depends upon the method of field excitation adopted
AC generators have a varying waveform which is sinusoidal in nature, whereas a DC output is linear.
AC generators have a varying waveform which is sinusoidal in nature, whereas a DC output is linear.
DC generators require more time and material to make. Because of this, it will be cheaper to purchase an AC generator. DC generators are typically a better product as well, and you get what you pay for.
Windstream Power and several other companies like it sell DC generators. You can buy them online or there are several stores where DC generators can be purchased. There do not seem to be any stores which sell them locally, but you can buy DC Generators online at http://www.windstreampower.com
DC generators are always useful in case of power outages. Many commercial companies use generators as back up units. DC generators are also energy efficient.
Most diesel generators are designed to produce alternating current (AC) electricity. However, there are some diesel generators that can also produce direct current (DC) electricity with the help of rectifiers or inverters.
There are several online stores selling DC generators. Many household appliance store will also have generators.

conclusion of dc power supply 9V
Batteries and generators provide DC, Direct Current electricity.
The two main types of generators used to produce electricity are AC (alternating current) generators and DC (direct current) generators. AC generators are commonly used in power plants and homes, while DC generators are typically used in portable devices and certain industrial applications.
List out the conditions to be satisfied for running two or more DC shunt generators in parallel?
