Units. The dimension of power is energy divided by time. In the International System of Units (SI), the unit of power is the watt (W), which is equal to one joule per second.

Electrical energy defines the energy generated due to the movement of charge carriers in a conductor. While electrical power specifies the rate of consumption of electrical energy by a device. The SI unit of electrical energy is Joules. But electrical power is measured in Watts (or KWh).

Power is a function of voltage times the volume of electrons (current). Power is the ability to do work and is measured in Watts. The higher the voltage the more power you have with the same current (Watts (power) = Volts x Amps.

Originally Answered: What is the relation between mass and energy? Einstein's theory of special relativity (1905) shows that matter (as mass) and energy can be converted into each other according to the famous equation E = m c*c where E is energy, m is mass, and c is the speed of light.

Power in general is defined as energy over time. Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s.

The relationship between power and frequency is inversely proportional to each other .

Power Formula. Power is a rate at which work is done, or energy is used. It is equal to the amount of work done divided by the time it takes to do the work. The unit of power is the Watt (W), which is equal to a Joule per second (J/s).

Power is how fast energy is used or produced. A watt is a unit of power. A watt (W) is a joule (J) of energy used or produced per second. In 2010, the average US power use was 3.3 terawatts, or 3,300,000,000,000 watts.

Watts are a measurement of power, describing the rate at which electricity is being used at a specific moment. For example, a 15-watt LED light bulb draws 15 watts of electricity at any moment when turned on. Watt-hours are a measurement of energy, describing the total amount of electricity used over time.

Work = force * time * distance. ... When work is done, energy is transferred between systems, or transformed from one type of energy into another type. Energy shares the same units of measure as work. The SI unit of work or energy is the joule.

There isn't any relation between time and mass in speical relativity: mass is a Lorentz invariant, the same in all reference frames, time is the fourth component of the position 4-vector. Similarly, energy isn't a Lorentz invariant-it's the fourth component of the energy-momentum 4-vector.

There is no relationship between distance and time other than in Einsteins theories of Relativity which are not recognized as part of physics by Nasa, Cern and The Standard Model of Physics. They are two natural variables that are independent or perpendicular to one another but changes are correlated by the constant c.

work done = force × distance moved in direction of force. change in gravitational energy = mgh. power = work donetime taken, power = rate of energy transfer. power = force × velocity.

With power and energy, power is units of energy divided by time. The same difference as distance and velocity. The units of power are watts, the units of energy are joules. A watt is one joule divided by one second.

In a nutshell, watt-hours measure amounts of energy for a specific period of time, and watts measure rates of power at a moment in time. A common analogy for watts and watt-hours is speed and distance. ... Similarly, if a 60 W light bulb is on for one hour, then that light bulb will have used 60 Wh of energy.

Since the energy goes up as the frequency increases, the energy is directly proportional to the frequency. Because frequency and wavelength are related by a constant (c) the energy can also be written in terms of wavelength: E = h · c / λ. When the energy increases the wavelength decreases and vice versa.

Electric power is the rate at which a device changes electric current to another form of energy. The SI unit of power is the watt. Electric power can be calculated as current times voltage. Electrical energy use equals the power of the appliance multiplied by the amount of time the appliance is used.
