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 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 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 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.
Are there any connectors your system needs the power supply doesn't have?
Most often, power supplies for any type of equipment is givin to you when you buy what the power supply is for.
What are different type of regulated power supply?
switchinglinearferroresonant-transformer
How capacitor works in electrical fan?
in a ceiling fan the capacitor is used to give the starting torque to motor for run. because we need a rotating type of magnetic field to the motor to run. once the motor run it become running even we disconnect the capacitor. by using the capacitor we produce the electrica difference(phase angle) between the two current taking by capacitor and the motor winding.
