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.

How many lumen's in a 150 watt flood light?
The number of lumens produced by a 150-watt floodlight can vary depending on the efficiency of the light source. However, as a general estimate, a 150-watt floodlight typically produces around 1600 to 1800 lumens. This can vary based on the type of bulb used, the design of the fixture, and any additional features such as dimming capabilities.
Do a 12 volt 50 watt bulb and a 230 volt 50 watt bulb draw the same current?
No, they do not draw the same current. The current drawn by an electrical device is determined by the power (Watts) and voltage (Volts) using the formula: Current (amps) = Power (Watts) / Voltage (Volts). So, the 12 volt 50 watt bulb will draw higher current compared to the 230 volt 50 watt bulb.
What is the incandescent equivalent of a 40 Watt halogen bulb?
A halogen bulb IS ITSELF a type of incandescent illumination source. A 40 Watt traditional incandescent bulb usually emits about 400 to 500 lumens while a halogen may emit close to twice that. So a 25 W halogen might give out as much light as ah older style 40 W bulb.
How many amps are required to run a 240-volt 5500-watt water heater element?
Current (Amps) = Power (Watt)/Voltage (V) Therefore a 4500W heating element will draw 18.75A = 4500W/240V
How much is 1 watt in degree celsius?

Who discovered the watt?
James Watt discovered watt.
How many giga watts is a exa watts?
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
What is the Homonym for watt?

What is gegawatt?
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 .
