Why DC supply is used in control circuit?
dc supply is used for control circuit because dc current is an independent source .
What is DC source?
a constant amplitude supply
What is DC source rating?
a constant amplitude supply
How you convert a power supply into 12v DC?
DC 12V power supply can convert 110/220V AC power source to 12V DC.
What are the applications of variable DC power supply?
variable dc supply are used to get desired amount of dc supply
Why choke used in dc drives?
choke is used before drives to reduce the source supply fluctuation problem , which will effect drives
Why transformer can not be used in dc supply?
The transformer cannot be used in the DC supply because it keeps on alternating its current, whereas the DC supply current should be constant.
Can we charge a phone with dc current?
Your mobile phone charger already have ac to dc converter , as ac supply can't stored. and you can charge directly with dc supply by maintaing volage of battery and dc source.
where is dc supply is used without ac supply?
If you are asking from where you can obtain a d.c. supply without using a rectifier supplied from an a.c. source, then the answer is that d.c. supplies are directly available from batteries or from d.c. generators.
Can a DC bulb be used with AC supply?
yes. because the normal bulb load involve only resistor. the direction of source is not considered
Why DC-DC converter is used in telecommunication power supply instead of inverter?
DC-DC conversion offers the advantage of a bifurcated power source. AC can be rectified and filtered to supply power under normal conditions at say, 17VDC fed to a 9VDC regulator to power the circuit. A 12VDC battery can serve as an alternate feed to the circuit for times when the AC source fails -- and it is connected to the same 9VDC regulator. Another benefit of DC-DC conversion is isolation to the circuit from noisy events.
What is the principal component used to regulate the DC voltage in a DC power supply?
transistor
