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).

What is the equation for energy transferred by an electrical appliance?
Energy = power x time. If power is in watts, and time in seconds, energy will be in joules.
What is a measure of electrical energy called?
Electrical energy is measured in the same units as any other type of energy: joules.
Electrical potential energy?
Electrical potential energy is the energy associated with the magnitudes of the charges on electrically charged particles and the positions of the particles relative to one another. The closer two particles with the same charge are, the greater the potential energy. Therefore, the particles have the greatest electrical potential energy at position 1. Electrical potential energy is similar to gravitational potential energy. Both energies exist because the relative positions of two objects give the objects the ability to do work.
A couch potato might consume 6 million Joules of energy in a day What is this rate of energy consumption in watts?
Rate of energy= 69.4 watts.
The power of a light bulb that converts electrical energy at a rate of 100 joules per second is what?
100 joules/second = 100 watts.
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.CommentYou 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.
Is the length of time an electrical load is on proportional to power or energy?
Power (watts) is amperes times voltage, or joules per second. Energy is joules, or watt-seconds. The length of time an electrical load is on is proportional to energy, not power.
How many joules of light energy are in 1440 watts of electrical energy?
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.

What is the speed at which energy is transfered?
That is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = Watts
60-watt light bulb in jouls?
A Watt is a Joule per second. Joules measure energy and Watts measure power, which is the rate of energy used. Therefore, if you use a 60 Watt light bulb for 10 seconds, you consume 600 Joules.
What is a measurment of electrical energy?
Electrical energy is measured in the same units as any other type of energy: joules.
What is used to measure of electrical energy?
All energy is measured in joules.
What is a measure of electrical energy called?
Electrical energy is measured in the same units as any other type of energy: joules.
How much power is used when 600J of work are done in 10s?
60 W
How much energy does a 100-w light bulb use in 10 s?
Power = energy / time, in SI units: watts = joules / seconds. Solving for energy: Joules = watts x seconds.
How many joules equals 1 kilo amp?
This is not a valid question by itself. Joules are units of energy, while Amps are units of electrical current. However, if you also know the Voltage of the electrical current, you can multiply the Current[Amps]*Voltage[Volts] to get the Power in Watts. Watts are equivalent to Joules per second. If you then know the amount of time of the current flow, you can calculate the total number of Joules by multiplying the Power[Watts]*Time[seconds] = Energy[Joules] .
