How many watts in a Kva?
A VA is a volt-ampere, or volt-amp, and a kilo (K) is one thousand. This makes a KVA a kilovolt-ampere, or kilovolt-amp. If we have 1,000 volt-amps, and one volt times one amp is equal to one watt (W), which it is, 1,000 volt-amps is equal to 1,000 watts, or 1 KW. All that said, 1 KVA is equal to 1 KW.Sometimes in an ac system, the watts is less than the volts times the amps, and in that case the watts is equal to the volts times the amps times the power factor. The power factor is less than one. The power factor for a typical electric motor is 0.7, so then there are only 700 watts in a kVA.
How many ampere in 240 volt with 100 watts bulb?
Current (amps) = power (watts) / voltage = 100/240 = 0.42 amps
What does half a volt equal in watts?
You need to know amps to answer this... Amps x Volts=watts
How many watts are in one volt?
There are zero volts in a watt. Watts are the product of amps x volts. Without stating the voltage and amperage, the wattage of a device can not be calculated.
What is the maximum volt-ampere loading permitted on a 20-ampere branch circuit with a continuos load is?
The wattage of the circuit presuming that the circuit voltage is 120 volts. 20 x 120 = 2400 watts. Circuit loading on a continuous load is 80% so 2400 watts x .8 = 1920 watts
How many watts need for seven ampere's and 120 volt's?
770 watts.

How many watts in 1 ampere 230 volt?
Watts = Amps X Volts Grab your calculator!
Volt ohm ampere and watts are terms associated with what?
ohm is used to measure resistance of electric current. Ampere is used to measure electric current. volt is used to measure voltage.
How much is 900 watts?
About as much as 15 typical (60watt each) light bulbs together. Or expressed in horsepower: about 1.2Hp Mains volts and ampere: 230 volt at 3.91 ampere = 900watt 110 volt at 8.18 ampere = 900watt
How many ampere in 240 volt with 100 watts bulb?
Current (amps) = power (watts) / voltage = 100/240 = 0.42 amps
How do you convert volts to mva?
Do you mean 'megavolt ampere' (MV.A) or 'millivolt ampere' (mV.A)? By using the incorrect symbol ('mva'), this is not clear.To determine the apparent power, in volt amperes, you divide the true power, in watts, by the power factor of the load. One volt ampere is one-millionth of a megavolt ampere ('MV.A' -not 'mva') -assuming you don't mean 'millivolt ampere' ('mV.A')!
What is a volt-ampere the product of?
A volt - ampere is the unit for the product of voltage and current. This is power. Power = voltage x current. The unit of power is more usually called the watt. Volts x amps = watts.
If an EMF of 1 volt causes a current of 1 ampere what is the resistance of the material through which the current is flowing?
1/1 = 1ohm MR. volta [italian] Determined that it would take 1 volt to pass 1 amp trough a 1 ohm resistor MR ampere [ french] Ditermined that it would take 1 ohm and 1 volt to pass one ampere MR ohms [english] determinaed that for 1 volt and one ampere the resistance must be 1 ohm. mr watts determined that the product of volts x ampere will equal one watt [power]
500 watts is how many amps?
The same number as 250 oranges is apples. A watt is a volt times an ampere.
One ampere is equal to?
120 Watts in a 120 Volt system and 240 Watts in a 240 volt 1 phase system and 415 watts in a 240 Volt 3 phase system.AnswerThe SI unit for electric current, the ampere, is defined as 'that constant current which, if maintained in each of two, straight, parallel conductors of infinite length and negligible cross-sectional area, and placed one metre apart in a vacuum, would produce between them a force of 2 x 10-7 newtons per unit length'.
How many kilowats are in 1 amp?
Watts (or kilowatts) and amperes are used to measure different things. Watts is a unit of power; ampere is a unit of current. The relationship (for direct current) is: watt = ampere x volt For AC, the relationship is a bit more complicated: watt = ampere x volt x power factor However, the power factor is often close to one.
