What do watts measure?

Answer 1

The watt (W) is the SI derived unit of power, equal to one joule of energy per second.

Power, rated in watts, is the rate of transfer of energy. This can be heat/time or work/time. Either way, a watt is a joule per second.
Power

Answer 2

energy is usually expressed in joules, if you want to know specifically kilowatts, as per your question, kilowatts are a representation to an amount of power consumption or output, not necessarily "energy". 1 kilowatt is 1,000 watts, which is roughly equal to 1.34 horsepower,

1 watt=1joule per second

In terms of mechanical energy, one watt is the rate at which work is done when an object is moved at a speed of one meter per second against a force of one newton. one kilowatt is the same, but with one unit x1000, so either the same object is travelling 1000 meters, with the same friction, or 1000x the friction to go the same 1 meter distance.

basically, this power consumption is the same if the object is travelling slower, with more resistance, as a submarine, or faster with less resistance, as a space ship without gravititational interference

but to answer the question, no. energy is expressed in joules, and while kilowatt is a type of energy, it is not exclusive for all energy types.

Answer 3

Watts are electrical power.

It is simply the product of the applied voltage and the current flowing in a circuit.

If you connect a battery to a bulb it lights up

If it takes 2 Amperes of current and the voltage of the battery is 4 volts the wattage will be 2A times 4V = 8watts of power( 8W)

This is for DC circuits. Household AC is a bit different. It can be the same sometimes.

Answer 4

Nope. "Kilowatt" is a rate of using electric energy. The longer you keep using

a kilowatt, the more energy you'll use, and the higher your electric bill will be.

The unit of energy that appears on your bill is the "kilowatt-hour". It might

surprise you to learn that the kilowatt-hour is the amount of energy you use

if you use energy at the rate of one kilowatt and you keep it up for one hour.

Answer 5

Kilowatts is the rate of energy or power. Energy itself would be measured in kilowatthours.

Answer 6

Volts and watts are both names of units used to measure electrical energy. The abbreviation kW stands for kilowatts, which is 1000 watts.

Answer 7

electricity is measured in volts, watts and amps... power in measured in watts

Answer 8

Well, for electricity, the unit IS the watt. So yes, the watt.

Answer 9

Electrical energy is measured in kilowatt-hours. A power of 1 kilowatt used for 1 hour equals 1 kilowatt-hour, also known as a Unit.

Answer 10

-- Power

-- the rate at which work is done

-- the rate at which energy is transferred or dissipated

(Three ways of saying the same thing.)
