∙ 8y agoA capacitor can be used to store energy, these are often found in power supplies. A capacitor has a voltage that is proportional to the charge that is stored in the capacitor.

Why use capacitors on fan motors?
capacitor stores charge ,so we use capacitor in fan for continuous voltage supply.
3 ways to reduce power supply ripple?
Increase filter capacitors. Series inductors Semiconductor regulator 3 phase lines instead of single phase
Can i reduce electric bill by improving power-factor?
For a residential consumer, power-factor improvement has absolutely no effect on one's electricity bill. Adding power-factor improvement capacitors at the point of supply will have absolutely no effect upon the operation of the load circuits, but it may act to reduce the supply current. But reducing the supply current will not reduce one's energy consumption.
How do you wire start and run capacitors into an electric motor?
Connect your start capacitor in series with the start winding.Connect the run capacitor in the common terminal and Line 1 of the power supply.
What function does a capacitor serve in an auto transformer?
An autotransformer does not normally use any capacitors as it is a transformer with one winding and the lower voltage is taken from a tap part-way up the winding. A capacitor could be added if there is a concern about the power factor presented by the autotransformer to the supply.
Why does my LCD TV have no power all of a sudden?
Could Be a fuse on the Circuit Board or The Power Supply Capacitors are bad.
1 How long does a power supply retain power after the computer is turned off?
A computer power supply has capacitors and can maintain power for a along time. See:http://en.wikipedia.org/wiki/Capacitor#Hazards_and_safety
How do you get the buzz out of the Magnivox radio 1970s?
Here's one possibility ... no guarantee: Radios of that era used large-value electrolytic capacitors in their power supply filters. These capacitors can deteriorate over time, allowing AC-ripple out of the power supply, which is then clearly audible in the audio stages. Take the radio to a TV-repair shop or a friend familiar with electronics construction, and ask them to replace the electrolytic capacitors in the power supply.
Why does your tcl tv has no picture and has no sound but the on and off indicator flashes?
It sounds like you have a power supply problem. The capacitors on the switched mode power supply have changed value or failed completely. Replace or repair the power supply section.
What is theloud buzz when you turn on radio Magnivox early 1970 model 2540A?

Why is your consort ev 265 power supply reading low current and power?
A Consort EV 265 power supply may be reading low current and power if the capacitors are failing. They will be unable to provide the needed power and operate consistently.
Why use capacitors on fan motors?
capacitor stores charge ,so we use capacitor in fan for continuous voltage supply.
What danger is posed to a technician by opening a power supply even after it has been unplugged for an extended period of the time?
The capacitors in the power supply may still be 'charged' - and give off a powerful shock if touched.
Can power be stored in capacitors an be utilize to supply a small home with power?
In theory, yes. In practice, no because the capacitors needed to do this would be several times the size of the house and much too expensive to purchase. Use rechargeable batteries. Because they store energy in chemical form instead of just an electrostatic field they can store orders of magnitude more energy than capacitors can.
Why is your consort ev265 power supply reading low current and power?
A Consort EV265 power supply will begin reading low current and power during component failure like capacitors and resistors. When the appropriate amount of power is not flowing, readings and power output will fluctuate.
What could be some reasons for a Samsung television not turning on?
Apart from the obvious, checking the power cord is plugged into a live socket, the most common cause is a faulty power supply within the TV.All modern TVs use a switched mode power supply, to change the mains voltage to semi-conductor levels. 12v, 5v and sometimes other lower DC voltages.When in standby, a small voltage is provided, to keep the infra red detector live and ready to come out of standby. This keeps the power supply main voltages switched off electronically, to conserve power. The control of the main power supply is reliant on electrolytic capacitors to store the correct potential and feed back to a control circuit, commonly a dedicated IC. If the capacitors do not function correctly, the control circuit keeps everything OFF to protect from fires and damaging the rest of the circuitry from incorrect voltages.Electrolytic capacitors dry out with age, change value and sometimes 'bulge'. This will stop the power supply from working. Find a replacement board, or replace faulty capacitors on the board.
How does a filter operates in DC power supply?
It removes the remaining AC ripple after the rectifier, using capacitors (to bypass it to ground) and/or inductors (to block it).
