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 a power supply dangerous even after the power is disconnected?
Power supplies have large capacitors in them. These capacitors store electricity in them even when mains power is shut off. If you were to touch the connections on the bottom of the capacitors, you could receive a potentially lethal shock. For this reason, you should never disassemble a power supply unless you have received training in how to properly discharge the capacitors.More answersBecause of the big electric charge held within the capacitors inside it.Computer power supplies have very large capacitors (elements that store charge) that could give you a very powerful shock if you managed to discharge them. They're like batteries that let go of all their charge at once.Capacitors store energy (power) for an indefinite time. Touching both leads of any charged capacitor can give you a real good jolt.For example, the tube of an old-fashioned television set is a giant capacitor in electronic terms: even though a TV may have just been switched off and unplugged, there may still be about 40,000 volts stored up in its cathode ray tube (CRT) that will cause great harm unless proper precautions are taken to discharge it safely.
Why are discharge resistors connected across large industrial capacitors?
A: Discharge or bleeder resistance are there for only one reason to bleed the charge when the power if off and unless there is a paths for those capacitors to be discharged the power stored there can be lethal to humans or detrimental to the circuit
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.
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).
Why are capacitors required to be in capacitor banks?
Capacitor banks are used to control the power factor in a power system. By connecting suitable capacitors the power factor can be controlled / maintained at a desired level. The requirement of a capacitor changes as the load changes dynamically. The same amount of capacitors can not maintain the desired power factor all the time. To be able to connect only the required number of capacitors, multiple (bank of capacitors) capacitors are included in a system. An automatic controller senses the actual power factor and connects and disconnects the capacitors from the bank as required
How is energy source stored?
The answer depends on the source. Wood is stored in stacks. Coal is stored in piles or bins. Oil and gas is stored in tanks. Electricity is stored in batteries or capacitors. Water power, solar power and wind power can not be stored in any simple way if at all.
Why is a Power supply of a computer still dangerous after disconnecting the power?
If you mean "disconnected' instead of "discovered" then it is because there is still power stored in the capacitors both in the power supply and on the motherboard. If you have any small lights on your computer, try unplugging the computer then pressing the power button. The lights should go on for a second and then go out. This action should discharge the capacitors.This can act the same as static electricity stored in your body in that it can connect two wires and cause a short circuit and damage components.For more information see the answer to the Related question shown below.
Why do ac radios still have a soft hum after being turned off?
When you turn the radio off, you interrupt the AC supply from the wall outlet to the radio's power supply. If there's energy stored in the power supply components at the time, then the radio continues to operate on that energy. An AC power supply typically includes large-value electrolytic capacitors, which continue to power the radio for a short time until they're discharged.
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.

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.
What is capacitor bank.?
A Capacitor Bank is a group of several capacitors of the same rating that are connected in series or parallel with each other to store electrical energy . The resulting bank is then used to counteract or correct a power factor lag or phase shift in an alternative current (AC) power supply. They can also be used in a direct current (DC) power supply to increase the ripple current capacity of the power supply or to increase the overall amount of stored energy.
