How many people still use DC electricity?
If you are talking about DC power line electricity, it is no longer used in homes or industry however many electric rail systems (e.g. trolley, highspeed trains) use DC electricity as DC motors have several advantages for motive power compared to AC motors. A few very long transmission power lines use DC electricity, but the DC is converted back to AC electricity before being distributed to customers. Certain industries (e.g. electroplating, aluminum refining) use DC internally, but they use large rectifiers to convert 3-phase AC to DC electricity when it enters the plant.If you are talking about electronic equipment (e.g. radios, computers, cell phones) these usually contain batteries. Everyone using battery powered electronics (or lighting, toys, cars, UPSs, etc.) uses DC electricity, because that is the way batteries provide electricity.Nearly everyone uses DC electricity, in battery powered devices.
What is a DC generator the same as?
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.
What supplies direct current?
device what produce dc are battrey genorators
Is dc voltage the same as millvolts?
The v in vdc stands for volts. The dc stands for direct current. This is a voltage that you find in batteries and is not to be confused with AC which is alternating current which is the electricity in the utility grid that feeds your home electricity.
Why DC electricity does not have poly phase?
There is no such thing as phase in DC as phase requires AC. To have two or more things out of phase requires them to be changing. Only AC does that. DC is steady state.
