Watts = Amps x Voltage x Power Factor
Hence to compute watts you need to know voltage and power factor. If you have a pure resistive load like a light bulb power factor = 1 and can thus be ignored. If you are asking about residential power, the voltage is 120 VAC so the computation is now trivial.

How many watts in one ampere?
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).
How many watts of electrical power equal one horsepower?
One horsepower is approximately equal to 745.7 watts.
How many tera watts in one giga watt?
There are 1,000 terawatts in one gigawatt. This is because one terawatt is equal to one trillion watts, and one gigawatt is equal to one billion watts.
What is one quadrillion watts equal to?
One quadrillion watts is equal to one million gigawatts.
How many watts equals 1 ampere?
The relationship between watts and amperes depends on the voltage. For a direct current (DC) circuit, the formula is Watts = Amperes x Volts. So, for a circuit with 1 ampere at 1 volt, the power would be 1 watt.
How many microamperes are in an ampere?
One ampere is equal to 1000000 microamperes.
How many watts of power are equal to 1 horsepower?
The definition is that 746 watts equal one horse-power.
A kilowatt-hour is equal to how many watts of electricity used for one hour?
1,000 watts
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')!
How many watts in a Kva?
1 kVA is equal to 1,000 volt-amperes. The conversion between volt-amperes (VA) and watts (W) depends on the power factor of the load. For resistive loads and a power factor of 1 (unity), 1 kVA is equal to 1 kW (kilowatt). However, for loads with different power factors, the relationship between kVA and kW varies.
How may watts in one ampere?
Watts is a unit of power, whereas Amperes is a unit of current. They're related though, along with Voltage, Resistance etc. But they're not the same thing, so to answer your question: There are no watts in an ampere! Power (W) = Voltage (V) x Current (I)
How many kilo watts does it take to equal one horsepower?
It takes 0.7462 kW to equal one horsepower.
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.
What does one milliamp equal?
Milli means 1/1000, and amp is short for ampere, so that is 0.001 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 milliamperes are there in 15 amperes?
There are 1000 milliamperes in one ampere. Therefore, 15 milliamperes is equal to 15/1000 = 0.015 amperes.
How many coulomb one ampere?
One ampere is equivalent to one coulomb per second.
