How many volts can a capacitor hold. what would be the formula for a capacitor that holds 100 volts?
Miikee
The working voltage of a capacitor depends on the nature of the dielectric and its thickness. Most capacitors are marked on the case e.g. 500V wkg. or just 150V. Small components are colour coded; the code will tell you the capacitance, and the wkg voltage.

1 mega watt equals how many volts?
Watts, Volts and Amps are interdependent, but unique units of electricity. The formula is: Watts = Volts * Amps A megawatt is just 1,000,000 watts. At 1 volt that would be 1,000,000 amps At 1,000,000 volts that would be 1 amp.
If a heater takes 1200 watts at 120 VOLTS what would the amperage be?
I don’t know
How many volts watts and amps would an electric piano use?
Some where on the electric piano there will be a manufactures label. When you find it the voltage and amperage will be stated. To find the wattage use the formula W = Amps x Volts.
How many amps does a router use?
That depends on your router. The current draw of a router (or any other electrical device) can be calculated by: Amps * Volts = Watts If you know any two, you can calculate the third. If (for example) the router draws 750 Watts, and you know that it plugs into 120 Volts, then you can plug into the formula Amps *120 Volts = 750 Wats OR Amps = 750 Watts/120 Volts OR Amps = 6.25 If you would like the answer in volts it would then be about: 120
How many amps are in 280 watts with 120 volts?
W = Amps times Volts. A = W/V, A = 300/120 = 2.5 amps
Why would the meter show 5 volts when the main leads to the machinery aren't connected?
There is probably a capacitor in the machine which holds a certain amount of electricity for helping deliver an amount of current at start-up.
What effect will be produced on a capacitor of the separation between the plates is increased?
Nothing until the potential difference produces an electric field stronger than the insulation in the capacitor can take. Then it will spark over. For an air capacitor that is approximately 33,000 volts per centimetre in dry air, so for spacing of 0.25 mm the sparking voltage would be around 700-800 volts

How powerful of an alternator and a capacitor would be needed to run a 6000W Subwoofer system in a 1999 Dodge Intrepid?
6000 watts divided by 14.2 volts (12 volt car system operates near 14.2 volts), gives you 422 amps. You would need 4 alternators rated at 110 amps each to make 6000 watts of power at 12 volts. If the system were 24 volts, you would only need 2.
How do you calculate the current?
If the wattage of a load is known then the current can be calculated. Watts equals amps times volts. You would use the following formula, Amps = Watts/Volts.
If a heater takes 1200 watts at 120 VOLTS what would the amperage be?
I don’t know
You want to know what kind of capacitor you would need to drive a 2880 watt motor at 72 volts?
can,t be done with a capacitor alone current only flows when a capacitor is charaging or discharging. capacitors are used in motors for diffrent reasons some are cap start or cap run, or for power factor corection. you should make sure any capacitor is replaced with the correct voltage and amp rating.
What does uF mean?
uF is a measurment in electronics called Microfarad. You will typically see uF on Capacitors for example 400Volt 150uf would be a capacitor rated at 400 volts and 150 microfarad.
If you wanted a capicitor to hold 100 million volts what would you have to do to make it. Formulas. Materials. Schematics?
You would have to have a capacitor rated for 100 million volts, and you would have to have a 100 million volt power supply. Before even considering this idea, consider this; the limit of approach for a conductor at 500,000 volts, is 20 feet. This means that within 20 feet of a conductor where this voltage is present, it can arc to you and kill you. At 100 million volts, well, you're typical lightning strike is 100 million volts. The lightning bolt travels miles through the air which it ionizes.
What is the Watts of A generator rated at 220 Volts and 6Kva and what is Kva?
A 6kVA generator puts out 4.8kW (4800 watts) with a power factor of 0.8 Formula w (watts) x pf (power factor) = VA (volt amps) This generator will be able to draw a load of 20A (amps) 6kVA = 6000VA. Where watts is only a measurement of "real power" used (eg: Heater element) VA is a measurement of total current that will flow through a circut. (eg: capacitor) A capacitor does not use power (kW) but current does flow in a circut where capacitor is connected. kVA ratings would be used to size cables.
How many volts watts and amps would an electric piano use?
Some where on the electric piano there will be a manufactures label. When you find it the voltage and amperage will be stated. To find the wattage use the formula W = Amps x Volts.
How many milliamps in 48.8 watts?
Milli amps is a measure of current whilst watt is a measure of power. The missing element is voltage as the formula is:- Power = Voltage * Amps ie power in Watts is the product of Volts (in Volts) times Amps (in Amps)
