# How much power in watts will an led bulb consume if its energy is 6 joules?

Joules (energy) are not equivalent to Watts (power).

If something converts 6 Joules every second, it is 6 Watts. If it takes ten seconds to convert 6 Joules, its power is 0.6 Watts.

Multiply the Watts by the seconds to find the Joules.

You do not 'consume' power. Power is simply a rate; you cannot consume a rate! You consume energy; the rate at which you consume it is power.

Energy / time = powerIn SI units: Joules / seconds = Watts  Joules is a unit of energy; watts is a unit of power. You can't just convert it. The relationship between the two is: power = energy / time in units: watts = joules / second There is no conversion, as joules measures energy and watts measures power -two different quantities! Power is energy per time unit. It is measured in is Joules / second, also called Watts.Power is energy per time unit. It is measured in is Joules / second, also called Watts.Power is energy per time unit. It is measured in is Joules / second, also called Watts.Power is energy per time unit. It is measured in is Joules / second, also called Watts. Watts are a measure of power, Joules are a measure of energy. The energy is equal to the power times the time. So if you have a power of 5 watts running for 7 seconds, that is 5x7 Joules of energy, or 35 Joules. Looked at another way, power measures how fast energy is converted. So 35 Joules converted in 7 seconds would be 5 watts of power, but it would need 35 watts to convert that energy in 1 second. Just divide the energy (in joules) by the time (in seconds). Answer is in watts.Just divide the energy (in joules) by the time (in seconds). Answer is in watts.Just divide the energy (in joules) by the time (in seconds). Answer is in watts.Just divide the energy (in joules) by the time (in seconds). Answer is in watts.  Watt means joules/second. It refers to the amount of energy a device uses, in this case. Multiply the power (in watts) by the time (in seconds) to get the energy (in joules). Watts is a measure of power, which is the amount of energy in Joules flowing every second. Watts is energy output. Watts is joules per second. Joules is energy. Power = (quantity of energy transferred, used, or dissipated) / (time to do it) When energy is in joules and time is in seconds, power is in watts. 1 Horsepower = 746 watts= 746 joules of energy per second 5 HP MOTOR WOULD CONSUME ENERGY OF 1342800 JOULES IN AN HOUR.EXPLANATION :-1 HP = 746 WATTSTHEREFORE 5 HP = 3730 WATTS.= 373O Joules/sec (since 1WATT= 1 Joules/sec)=3730 x 3600= 13428000 Joules/ hour. I guess that would be power (energy per unit time), i.e. Joules per second, a.k.a. Watts.I guess that would be power (energy per unit time), i.e. Joules per second, a.k.a.

Power (watts) = Energy (joules) / time (seconds). Thus, Time (seconds) = Energy (joules) / Power (watts) = 90J / 40W = 2.25s You simply can't convert between units that measure completely different tings, in this case energy (for joules), and power (for watts). The general relationship is: joules = watts x seconds Or equivalently: watts = joules / seconds Power is energy / time. In SI units, joules / second, also known as watts. A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts. Watts means joules per second (joules / second), or equivalently, joules is watts times seconds.A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts.

Watts means joules per second (joules / second), or equivalently, joules is watts times seconds. To find the energy in Joules you multiply power in Watts by time in seconds. So the sum is 60 watts x 36,000 seconds, or 2,160,000 Joules 231,000 joules is an amount of energy, while watts are a measure of how fast energy is used or converted. 231,000 joules could be used by 1 watt running for 231,000 seconds, or 231 watts running for 1000 seconds, etc. Energy = power x time, so 1000 watts for 231 seconds is an amount of energy equal to 231,000 joules. Energy = power x time. If power is in watts, and time in seconds, energy will be in joules. Power = energy / time, in SI units: watts = joules / seconds. Solving for energy: Joules = watts x seconds.   ###### PhysicsEnergyMath and ArithmeticHome ElectricityUnits of MeasureScience Copyright © 2020 Multiply Media, LLC. All Rights Reserved.
