Electrical Power And Work
The work done on the charge is equivalent to the electrical potential energy change of the charge.
Electrical power and work. In this article we will learn all about the concept of work power and energy. What is electric power. T is the time in seconds s. In physics the rate of transfer of electrical energy by an electrical circuit per unit time is called electrical power.
Power is the rate with respect to time at which work is done. It is the time derivative of work. Its mathematical formula is expressed on a per time basis. Find the electric power of an electrical circuit that consumes 120 joules for 20 seconds.
The electric power p is equal to the energy consumption e divided by the consumption time t. E 120j. Work done is generally referred in relation to the force applied while energy is used in reference to other factors such as heat. If it s not lighting up the storm clouds overhead or crackling in a static spark at your fingertips then it s moving through the human nervous system animating the brain s will in every flourish breath and unthinking.
Power is defined as work done per unit time. Line installers and repairers install or repair electrical power systems and telecommunications cables including fiber optics. The rate at which the work is being done in an electrical circuit is called an electric power. Intro music atribution title.
Where p is power w is work and t is time. Sure you can flee from the world of crisscrossing power lines and live your life completely off the grid but even at the loneliest corners of the world electricity exists. E is the energy consumption in joule j. Electric power definition it is the rate at which work is done or energy is transformed in an electrical circuit simply put it is a measure of how much energy is used in a span of time.
If instead the force is variable over a three dimensional curve c then the work is. Electric power like mechanical power is the rate of doing work measured in watts and represented by the letter p. Andersen defines the terms energy work and power. If a constant force f is applied throughout a distance x the work done is defined as in this case power can be written as.
Line workers encounter serious hazards on the job including working with high voltage electricity often at great heights the work also can be physically demanding. P is the electric power in watt w. The term wattage is used colloquially to mean electric power in watts the electric power in watts produced by an electric current i consisting of a charge of q coulombs every t seconds passing through an electric potential voltage difference of v is. In other words the electric power is defined as the rate of the transferred of energy.
Like current power is a rate quantity. Thus electrical power like mechanical power is the rate at which work is done. Although most work full time during regular business hours some work.
