The real Watt's law is a hypothesis that states the sum of the latent heat of steam at any temperature of generation and the heat required to raise water from 0°C to that temperature is constant. It has been proven to be incorrect.
However electricity amateurs and even some instructors often incorrectly describe Watt's Law as stating P=VI (or P=IE). This is actually called "Power Law". The term "Watt's Law" should not be used here.

What instrument measures watts?
A wattmeter measures the amount of electrical power in watts being consumed by a device or circuit. It typically consists of a current and voltage measurement component to calculate the power in watts.
How do you find the actual wattage of an electrial component?
To find the actual wattage of an electrical component, you can calculate it by multiplying the voltage across the component by the current flowing through it, using the formula Watts = Volts * Amps. Alternatively, you can refer to the product specifications provided by the manufacturer, which usually list the wattage of the component.
How many watts is 1 VDC?
As watts equals volts times amps (ohms law simplified) you are missing part of the equation.. Let's say you are asking about how many watts is 1 amps at 12v then... If W = V x A then 1A at 12v = 12 watts
Formula for watts and amps?
power in watts = voltage in volts x current in amps. or power in watts = current in amps x (resistance in ohms) squared i think what you meant was power in watts =(current in amps)squared x resistance in ohms
How many amps is 20000 watts?
Hi. Power Law or Watt's Law of James Watt tells us that Power P (in watts) = current I (in amperes) X voltage E (in volts) or P=I x E, therefore I=P/E so just divide 2000w by 240v. Thanks.
What instrument measures watts?
A wattmeter measures the amount of electrical power in watts being consumed by a device or circuit. It typically consists of a current and voltage measurement component to calculate the power in watts.
How do you calculate the power used by a component when the potential difference is measured as 2.5volts and current is 0.2?
You need to know the resistance. Ohm's Law: Current = Voltage (in volts) divided by resistance (in ohms).
What are the release dates for L-A- Law - 1986 Watts a Matter 4-18?
L-A- Law - 1986 Watts a Matter 4-18 was released on: USA: 5 April 1990
What is the example of worded using ohms law?
amp*volts=watts
What is the kwh of 2 hp motor at 4500 rpm?
1hp = 746 watts, so 2hp would be 1492 watts, or almost 1.5 kw kWh does not convert to hp, as kWh has a time component.
What is the standard unit of power using ohm's law?
Ohm's Law has nothing whatsoever to do with power. Power is measured in watts.
Video card pulls how many watts?
The number of watts a video card requires depends on the type of card. However, on average, a video card uses wattage than any other component other than the motherboard. A graphics card can use 50 to 75 watts.
Define the Types of viscoelastic fluid?
These are types of fluid that exhibits both liquid and solid characteristics.The newtons law is usually assumed for viscous component and hooks law for elastic component.
For how long a battery of 20watts can give backup to a load of 5watts 2?
watts is an instantaneous measurement of energy. There is no time component. If you can produce 20 watts, then you can power exactly 20 watts for as long as that is being produced. If you have a 20 watt hour battery, you should be able to power a load requiring 5 watts for (20/5 =) 4 hours.
What does Raoult's Law state?
it states that for an ideal solution,the partial vapour pressure of a component is equal to the mole fraction of the component times the partial vapour pressure of the component when pure.
Which component of fiscal law gives Congress the power of the purse?
Amount
What is a body of law based on custom tradition and precedent set in past court cases?
Precedent is a component of common law
