Can i use capacitors to run a motor instead of a battery and how do i control the voltage to the motor?
You COULD use a huge capacitor, like a bank of 1-farad car stereo caps, to run a motor, because a cap is basically a battery that doesn't hold very much electricity. And if you did it, you'd control the voltage to the motor the same way you would with a battery--resistors, potentiometers, voltage regulators, whatever you like.I wouldn't do it, though, because a capacitor doesn't hold enough electricity to let the motor run for very long.Quick note: single phase AC motors all have "run capacitors" and "start capacitors" but those are something else entirely.CommentI don't think that you will ever find a 1-F (one farad) capacitor! A farad is a HUGE amount of capacitance! Practical capacitors are expressed in picofarads (10-12 farad) or microfarads (10-6 farad), never in farads! Bear in mind that capacitance is directly proportional to the area of its plates -so imagine how huge a 1-F capacitor would have to be!Running a motor from a capacitor is completely impractical. A capacitor will completely discharge in 5 CR, where Cis the capacitance of the capacitor and R is the resistance connected across its plates.So, let's pretend from one moment that you can find a 1-F capacitor and let's say the motor has a armature resistance of, say, 50 ohms (quite high!), then the capacitor would completely discharge in 5 x 1 x 50 = 250 s, or a little over 4 minutes!!!! However, if we used a capacitor with a realistic value of capacitance (in microfarads), then the discharge time would be measured in milliseconds! So, not much use for driving a motor!!!
A 5 uf capacitor has 5x10 -4 coulombs a charge stored in its plates find the voltage across the capacitor?
A5uf capacitor has 5*10-4 coulombs of charge stored on its plates
What is the value of capacitor voltage and current after 5 time constant?
After 5 time constants, capacitor voltage/current will be about 99.3% of the input step change.
An ideal voltage source charges capacitor in?
A: A voltage source Will charge a capacitor to 63% of its input value, The value to get there is stated a Resistance time capacitor as time. Mathematically it will never get there but engineering consider 5 times RC time constant as close enough,
What is the tolerance for capacitance of a start capacitor generally specified by the compressor manufacturer?
5/50mfd
What if 10 micro farad capacitor is connected to 5 micro farad capacitor in parallel what would be the result?
Since the total capacitance for capacitors in parallel is the sum of the individual capacitances. I'm sure that you can work it out for yourself!
Why wont my capacitor shut off?
Well it has 2 light bars and a section where it tells you how much juice it has...and it never goes off. I have a 5 Farad Lanzar Capacitor if that helps.
What mtx amp do you need to push your ts5512x2d speaker box?
JH1200 - Jack Hammer 1200watts - Mono Block Class D - Can wire two subs at 2ohms - Or 1 sub at 1ohms - I recommend using this amp for your TS5512X2D - It will blow you away - And don't forget to buy a capacitor - I'm using a 5 Farad Cap with the JH1200 and TS5512X2D - A normal rule of thumb is 1 Farad for every 1000 watts - I got the 5 Farad because it was only $10 more than the 3, but a 2 Farad should work just fine...
Why 1 farad capacitor generally is not available in the market?
I'm not sure where you are getting your information. Capacitors come in a large range - nano farad to several farad. The higher the farads, the bigger (in general) the capacitor will be. For example, amazon has a 1 F, 20 volt cap for ~76.00. I would consider this to be "generally available in the market". If you want a 1 farad cap for 120 volts, it's going to be substantially bigger than this one (20 volt is ~5 lbs.).

How do you install a hard start kit on an air conditioner?
Common wire of the potential relay goes to the compressor contactor. (5) Start wire of the potential relay goes to compressor run capacitor. (2) Run wire of the potential relay goes to the start capacitor. (1)
What is the difference in a 5 uf and a 4 uf capacitor?
1 uf (i.e. 5uf - 4uf = 1uf) Note: uf=micro Farads. A Farad is a unit of charge capacitance. You can think of it as charged electrons stored in a small package.
How do you wire a phone?
To wire a master phone socket (with capacitor) from the pole (usually orange white if not green black or blue pair ) wires go to screw terminals (for NTE5) or pins 2 and 5 doesn't matter which way round. To wire a secondary (no capacitor) NEW WIRE blue/white fleck -- pin 2 white/blue fleck -- pin 5 orange/white fleck -- pin 3 (bell) OLD WIRE blue -- 2 orange -- 5 brown -- 3 (bell)

How do you discharge 25 Kvar capacitor in 690Volt system?
This capacitor carries a current of 25,000/690 or 36.2 amps and its impedance (reactance) is 19 ohms. The capacitance is 1/(2.pi.50.19) or 0.000167 Farad, on a 50 Hz system. The time-constant is CR so that if a 20,000 ohm resistor is placed across the capacitor the time-constant is 3.3 seconds. The voltage is reduced by 99% after 5 time-constants or in this case 17 seconds. If the discharge resistor is permanently in circuit it dissipates 690^2 / 20000 or 24 watts.
What is the value of capacitor voltage and current after 5 time constant?
After 5 time constants, capacitor voltage/current will be about 99.3% of the input step change.
