What is the difference between the COMPONENTS of an AC machine and those of a DC

Question

Explanation / Answer

Actually when we consider the ac and dc machines -> Devices running off direct current are far more than devices running of AC current. -> DC provides a smooth supply of electricity,so it is good for things such as light or charging batteries. -> DC devices are polarized. This they certain the connection running from ground and one connection running from power supply. -> While AC current does not provide polarization, as the current reserves itself. -> AC is transmitting electricity for long distances. -> The devices and components that require the AC power doesn't need to be polarized. -> Devices that require very low voltages also need AC power. -> AC machines is also good at carrying very high voltages across power lines. -> AC motor has a simpler design and fewer parts.
