The watt is a unit of power. It is a Newton meter per second, or can be given as a joule per second. We often encounter it in electrical calculations, and it is the unit of power for applications there. The formula for power is given here:

P = I x E

In this expression, the power (P) in watts is equal to the current (I) in amps (or amperes, if you prefer) times the voltage (E) in volts.

The simplest example of a watt would be the amount of power that you would have if you had one volt at one amp of current. Or, to put it another way, 1 volt X 1 Amp=1 Watt. To go further, 12 volts at 1 amp equals 12 watts. This is for direct current measurement.

For AC voltage, it varies in that you would multiply the volts by .707 (AC RMS voltage), then multiply by the amps to get your watts total.

1W = 1 Watt, 1KW = 1 Kilo Watt = 1,000 Watt, 1MW = 1 Mega Watt = 1,000,000 Watt, 1GW = 1 Giga Watt = 1,000,000,000 Watt.

there is one Giga Giga watt in one Exa watt. So one Exa watt = one Giga Giga watt or 109 Giga watt or one Exa watt = 1018 watt and one Giga watt = 109 watt then one Exa watt = 109 Giga watt or one Exa watt = one billion Giga watt = one thousand million Giga watt

not gega watt ,it is gaga watt , you have to start from 1 watt 1000 watt = 1 k watt 1000 000 = 1 mega watt 1000 000 000 = 1 gaga watt example : your home need 5 k watt = 5000 watt , but this mega watt or gaga watt amount generated from huge turbine s ,to feeding cites needs in electricity demand .

a watt is a electric charge

There is no such thing as an 'electrical watt' and a 'thermal watt'. The watt is simply the SI unit for power, which is the rate of doing work or the rate of heat transfer.

No, the output of a 350 watt amplifier will not destroy a 500 watt capacity speaker.

No, you can not use a lower watt charger for a high watt or else the charge wont work

no a watt is a measurement of electricity

Neither. The word "watt" is named after the scientist, J. Watt.

Per watt, bulbs produce these amounts of light: Incandescent: 10-12 lumens/watt Halogen: 13-15 lumens/watt CFL: 50 lumens/watt

2300 watt-hours for every hour it operates. Watts x Hours = watt hours.

1 kilowatt = 1000 watt ==> 1 watt = 0.001 kilowatt

A watt is a measurement of electricity, usually pertaining to light. Light bulbs luminosity is graded by wattage, such as a 60 watt bulb, 100 watt bulb and so on. You would find a watt in a light bulb, to start.
