What type of capacitor is often used in power-supply circuits to filter the rectified AC?
The electrolytic capacitor is most often used in power supply circuits to filter the rectified AC.
How do you correct the power factor of a capacitor power supply?
Assuming the question refers to a capacitor-input power supply with a transformer, rectifier and reservoir capacitor, the problem is caused by the high peak currents which flow for only a part of the ac cycle while the capacitor is charging. Thus the poor power factor is not caused by the usual difference in phase between the voltage and the current, which is easily corrected. This being the case the power-factor can't easily be corrected and this type of power supply is confined to low-power applications of less than 1 kW.
What type of circuit would you find an electrolytic capacitor?
Many, but a near guaruntee would be any power supply. Electrolytic capacitors are the ones that look like batteries.
What type of waveform is produced by Ferroresonant power supply?
ferro-resonant power supply?
What is a capacitor regulator?
A capacitor regulator is an electronic circuit that uses capacitors to stabilize and regulate voltage levels in a power supply. It works by charging and discharging capacitors to smooth out fluctuations in voltage, ensuring a consistent output. This type of regulation is often found in low-power applications where simple and efficient voltage regulation is required. Capacitor regulators are typically less complex and cost-effective compared to other types of voltage regulators.
What type of induction motor is used in table fan?
Motor used in Table Fan is Split phase Motor(Continuous Running with Capacitor).It has Two winding Running coil + Starting Coil. Running coil connected Direct to Supply Starting coil Connected is series with capacitor than parallel with power.
What is the work of capacitor in sodium vapour lamp?
A sodium vapour lamp does not include a capacitor in its construction. Any capacitor associated with this type of fixture will be found where the ballast is located and not in the lamp itself.
What type of component holds its charge even after the power is turned off and the device is unplugged?
Capacitor
What is the function of a DC power supply?
By Khalid BetaniDirect current (DC) is the unidirectional flow of electric charge. Direct current is produced by sources such as batteries, thermocouples, solar cells, and commutator-type electric machines of the dynamo type.So the function of a DC Power Supply is to provide Direct current to various accessories of computer such as Hard Disk, Ram, Picture Tube or LCD, Mother Board, CD Rom/DVD Rom, etc, so that they function properly.
How do I decide what type of power supply I need when I'm building a desktop PC?
Power supply is dictated by your motherboard, simply get the power supply which matches the motherboards pin configuration.
What is floating capacitor?
A floating capacitor is a type of capacitor that is not connected to a fixed reference point, such as ground or a power supply, allowing it to maintain a potential difference independently. This can be useful in various applications, such as in analog circuits where isolation from other components is required. Floating capacitors can help in reducing noise and improving circuit performance by preventing ground loops. They are often used in applications like signal coupling, filtering, and energy storage.
What type of maintenance is required of a computer's power-supply to ensure that it remains in working order?
Computer power supplies today do not need daily maintenance. They do need a free air flow to circulate through the power supply to prevent overheating. If there is a filter to prevent dust fro getting in to the power supply, it should be kept clean so that air flow is not restricted. If parts of the power supply get too hot they may fail to function properly or they may burn out.
