A watt is a rate (speed) of using energy ... 1 joule per second.
Power (watts) is a measure of energy transfer over time, while energy (joules) is a measure of total work done. The formula to convert energy in joules to power in watts is: Power (watts) = Energy (joules) / time (seconds).
To convert joules to watts, you need to know the time over which the energy is expended. Since power in watts is defined as energy in joules divided by time in seconds, you cannot directly convert 7000 joules to watts without knowing the time duration.
There are 100 joules in 1 watt-second, so in 1 second, there would be 100 joules per watt. Therefore, in 100 watts, there would be 10,000 joules.
Watts measure the rate at which energy is generated or consumed per second. Energy output is the total amount of energy produced or consumed over a period of time. The relationship is that the total energy output is equal to the power (in watts) multiplied by the time duration.
To calculate the time it takes to perform 475 Joules of work with 25 watts of power, you use the formula: time = work / power. In this case, time = 475 Joules / 25 watts = 19 seconds. So, it will take 19 seconds to perform 475 Joules of work with 25 watts of power.
The relationship between amperes, volts, and watts is... watts = amperes * volts Confirming by looking at the fundamental units involved... watts (joules per second) = amperes (coulombs per second) * volts (joules per coulomb)
The relationship between amperes, volts, and watts is... watts = amperes * volts Confirming by looking at the fundamental units involved... watts (joules per second) = amperes (coulombs per second) * volts (joules per coulomb)
"59.4 watts" means "59.4 joules every second"
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 is joules per second, so 50 joules in 5 seconds is 10 watts.
Power (watts) is a measure of energy transfer over time, while energy (joules) is a measure of total work done. The formula to convert energy in joules to power in watts is: Power (watts) = Energy (joules) / time (seconds).

Those numbers describe the power used by the two bulbs, in other words how many joules of electrical energy they use per second. The 100 watt bulb uses 40 watts more.
There are 100 joules in 1 watt-second, so in 1 second, there would be 100 joules per watt. Therefore, in 100 watts, there would be 10,000 joules.

Power is measured in watts, or joules per second. So in 90 seconds, 1200 joules of work is equal to 1200/90 watts or 13.3 watts.
Power is energy / time, energy is power x time.This is similar to the distinction between distance and speed: speed = distance / time; at constant speed, distance = speed x time.Enery is measured in Joules, power is measured in Joules / second, a.k.a. "Watts".
