Why dc series motors cannot be used in home?
DC series motors run on DC power. Homes have AC power, not DC power. You could use DC motors in homes if you have a power supply or use a battery, but it is usually more cost effective to use an AC motor.
Why you use dc supply in generator protection panel?
The DC supply may supply power to trip breakers, or to power the protective relays.
How can a radio use both DC and AC?
Radios use DC power supplies to operate. If a radio is powered from a mains AC supply, a power supply circuit will convert the AC supply to DC. Therefore, a radio may have both a DC and an AC power input but ultimately, the internal circuitry will always use DC.
Why can't we use DC supply in home?
in our home most of the electrical appliances can work only on ac supply e.g. tubelights, fan, refrigeratorsand so on.else we can also say that dc supply is costlier then ac for the same amount of power.
What are the applications of variable DC power supply?
variable dc supply are used to get desired amount of dc supply
What does filter do in a transformer?
A transformer does not use a filter. You may be asking about the use of a filter in a power supply. A power supply uses a filter to change pulsating DC from the rectifier into smooth DC for the circuits that the power supply powers.
What kinds of electronics use a DC power supply?
Almost all digital electronics use a AC to DC power supply. Digital electronics cannot handle AC. all electronics device having battery powered are using DC power supply http://www.wzmicro.com
Full form of DC power supply?
DC Power is Direct Current Power Supply.
Why does we use 250ohms with power supply for the instrument calibration?
We use the 250 ohms with the power supply because the internal resistance of a DC power supply is insufficient to develop a resistance.
Is the metro rail train using ac or dc power supply?
dc power supply
What is the value of ripple in the ideal dc power supply?
In an ideal DC power supply, there is no ripple.
What the conclusion that can take in multiple dc power supply?
conclusion of dc power supply 9V
