What in VERY simple terms is a Watt and how is it used in everyday household use?

Answer 1

When 1 Joule of energy is spent in 1 second, the power is said to be 1 Watt.
In everyday household use, Watt is used to measure the power of electrical appliances. That is to say, if an appliance is labeled as 220W, it means that the appliance spends 220 Joules of energy(electrical) every second.

Answer 2

You had current (amps) and voltage explained in a previous question. You obtain wattage (power) by multiplying voltage by current. Since the voltage in your house is constant, the higher the rated power of an item, the more current it draws. For example a 100 watt light will use more current than a 60 watt lamp. Consequently your electricity bill will be greater

Answer 3

A watt is a unit of power=to I*E(voltage times amperage(current) or I^2 * R (Amperage squared times Resistance(ohms)) .Electric companies charge based on Killowatt(1000watt) Hours used.

Answer 4

Watts are measurment of power (joules per second)

eg. Power = work Done(Joules) Divided by time (secs)

Power(J/S or W) = 10(J) divided by 5 (secs) = 2 Joules per second/Watts

Work done(J) = Force(N) x Distance (M)

Answer 5

Watt is a mearsurement of power, it is used mostly in lightbulbs in everyday use.

Answer 6

Just use Ohms law.... Watts = Amps x volts...

Volts = Amps x resistance ( ohms)

Answer 7

1 W = { (1kg * m/s2 ) * ( 1m) ] / 1 s = (1N * 1 m) / 1s = 1 J / s

one watt equals 1 kilogram meter persecond squared times one meter all divided by one second

1 kilogram meter per second squared equals one Newton (Force)

1 Newton times one meter equals 1 Joule (energy)

one Watt (power) equals one newton times one meter all divided by one second or one Joule divided by one second or the amount of energy exerted divided by the time it takes to exert.


a Watt (named for a guy named: Watt) is a unit of power. Power is the amount of energy you can perfom divided by the time it takes you to perform it. If you climb ten stairs you use X joules of energy. If you climb faster you use the same energy but more power.

1 Watt equals one Joule/ one second.

1 Joule is a measurement of energy. Energy is "the ability to do work" meaning the ability to move something. mathematicaly work = energy. work is force times distance. If you push really hard on a wall, and it goes nowhere you are exerting lots of force but doing no work. but if you pick up a pebble you are exerting a small amount of force but doing more work than pushing really hard on the wall because you are moving the pebble. you multiply the little force you put on the pebble times the distance you moved the pebble and you get the work you did or the energy you used.

One Joule is One Newton (named for Isaac Newton) times one meter (about 3 feet).

A newton is a measure of how hard you push. it is equal to one kiligram times one meter/second/second or one meter per second squared.

a kilogram is a measure of mass (not weight and here's the difference. if you weigh 100 lbs on earth you have a mass of about 222 kilograms. on earth you can convert pretty easy. but on the moon you would weigh 16 pounds on the moon, however since you didn't loose any molecules, you have the same mass. 222 kilograms)

Anyway you take an objects mass and move it so that it is speeding up or slowing down (accelerating) and you an calculate the force on it.

This is important. newton's second law says F=ma (force equals mass times acceleration) meaning force is only exerted if an object is speeding up or slowing down. If an object is sitting still or going at a constant speed the forces on it are ballenced and there is no net force. you may be pushing your car hard to keep it rolling but if it is going at a constant speed the friction in the wheels, and from the road is acting against you balancing the car. but if it rolls down a hill the force of gravity will overcome the frictional forces acting on the car and cause the car to speed up or accelerate.

So the force on an object is equal to one kilogram times one meter/second (speed of the object) divided by one second (giving the rate at which the object speeds up)

So you take mass times speed divided by time (Force) times distance (to give you energy) and divide again by time and you get power: 1 Watt equals one Joule/Second = 1 Newton x 1 Meter/ one second = (1 kilogram ) times (1 meter/second/second) times (one meter) all divided by (one second)

Answer 8

SORRY WATT DID YOU SAY I DIDNT GET YOU THE FIRST TIME

Answer 9

a unit of electricity as in a 100watt bulb
