work is done at a rate of one watt when one ampere flows through a potential difference of one volt.
volts x amps = watts
So 1 watt is any ratio of volts x watts that equals 1.
1volt x 1amp = 1 watt
or
9v @ .11 amps = 1 watt
For "ratio of volts x watts" above read "product of volts x amps".
True for resistive loads. Beware reactive loads (capacitors and inductors) where current may not be in phase with the voltage. For a quarter cycle phase lag, the power is actually zero even if the current and voltage are large. Power Stations do not like supplying current to reactive loads.
AnswerIn AC, the product of current and voltage is called the apparent power of a load, and is measured in volt amperes. The watt is the unit of true power which is the product of current, voltage, and power factor (where power factor is the cosine of the phase angle) of a load.
One volt ampere is equal to one watt only when the current and voltage are in phase, which is the situation with a purely-resistive load. For all other loads, the true power is less than the apparent power (i.e. watts < volt amperes).
One ampere is equal to one watt in a system with a voltage of one volt. This relationship is defined by Ohm's Law, which states that power (in watts) is equal to current (in amperes) multiplied by voltage (in volts).
Zero volts equal one watt. Watts is the product of amps times volts. Without an amperage the voltage can not be calculated. The time constant has nothing to do with the equation.
Answer: Volts x Amps = Watts This question lacks sufficient information for an answer. It isnt. One watt is equal to one Joule of energy per second. Amperage is current, or to state it more accurately, the amount of electrons passing through a point in a second.
There is not enough information to answer your question directly... In order to determine how many volts it takes to make 4000 watts, you also need to know how many amperes there are. That is because watts is volts times amperes. For example, if you had a 120V system, you could divide 4000 watts by 120 volts to get 33 1/3 amperes.
There is no direct conversion between amperes and watts since they are different units used to measure different things. Amperes measure the rate of flow of electric current, while watts measure power. The relationship between the two depends on the voltage in the circuit using the formula: Watts = Volts x Amperes.
Amps, volts and watts are interrelated, but you need to do a little math. Amps * Volts = Watts
10000 watts / 220 volts = 45.4545 amperes
One ampere is equal to one watt in a system with a voltage of one volt. This relationship is defined by Ohm's Law, which states that power (in watts) is equal to current (in amperes) multiplied by voltage (in volts).
Watts is amperes times volts. There are one thousand milliwatts in a watt. Milliwatts, then, is milliamperes time volts, or amperes times millivolts, or something equally consistent.
Zero volts equal one watt. Watts is the product of amps times volts. Without an amperage the voltage can not be calculated. The time constant has nothing to do with the equation.

A device designed to run on 250 volts at up to 2 amperes.
The watt is a measurement of work done by an object at constant velocity and under constant force. 1 watt, therefore, is equal to 1 Joule per second.
You can convert amperes by using the formula: Amperes = Watts / Volts. To find out how much current 'X' watt of electrical equipment at 'Y' volt consumes per hour, you would need to divide the wattage by the voltage to get the amperes, and then also consider the duration of the consumption in hours.
That depends on the voltage. One amp flowing at a potential of 1 volt produces 1 watt of power (equal to an energy consumption of 1 joule per second). 4 amps flowing at a voltage of 250 volts produces a kilowatt of power. This would be enough to satisfy the individual needs of a lot of the electrical equipment around the house.
