all electronic circuits require some DC supply for operation. This supply is used to
put the individual active devices at a correct operation status to enable them to
operate at conditions as conceptualised by the circuit designer. If the DC supply is
Not correct i.e too low , high or Not of constant value the circuit is most likely to
malfunction with possibly disasterous consequences depending on the application.
What else can I help you with?
Why DC supply is used in control circuit?
dc supply is used for control circuit because dc current is an independent source .
What kind of supply is given to the circuit?
ac supply is given and then in the circuit rectifier converts ac to dc
What is use of RFC in Hartley oscillator?
it is a radio frequency choke which connects the dc supply to the circuit but isolate the dc supply from the high frequency oscillations generated in the feedback circuit
Why is a DC voltage supply used for energizing the tripping coil of an air circuit breaker?
If a fault in the system disconnects the substation, then batteries are the only supply available to trip the circuit breakers. Batteries, of course, are d.c.
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.
Which circuit element is used to block DC in an electronic circuit?
Capacitance will block DC
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.
Why dc source is used for dc supply?
it is only work on it so that used
What happens if dc supply is connected to incomer of transformer?
If a DC supply is connected to the incomer of a transformer, you effectively have a short circuit, because the DC impedance of a transformer (actually, any inductor) is quite low. You will blow something.
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 capacitance is not used in DC circuits?
as it acts ideally as open circuit for dc
What are the applications of variable DC power supply?
Variable DC power supplies are commonly used in electronics labs, production lines, and testing environments. They are used to power and test electronic devices such as electrical components, circuits, and sensors. Variable DC power supplies are also used in research and development for prototyping and experimenting with different voltage levels.
