Formula of work done in electricity
WebThe current formula is given as below: I = 2.2 A Therefore the amount of current flow is 2.2 A. Q.2: An electrical lamp lights for 8 hours a day. It … WebThe work done on the charge is equivalent to the electrical potential energy change of the charge. Thus, electrical power, like mechanical power, is the rate at which work is done. Like current, power is a rate quantity. Its mathematical formula is expressed on a …

Kinetic energy is equivalent to the … WebApr 15, 2024 · Formula of Work done. Work done is the multiplication between the net applied force and the displacement of the object. Work done = Net force × Displacement. If a net force F displaces a body by r in the direction of applied force, then the equation of work done is, katex is not defined. But, this is not the general formula.
WebMar 31, 2024 · This formula works for any form of power measured in watts, but electricity is the most common application. Advertisement. ... Kinetic energy is equivalent to the amount of work done to accelerate a stationary object to a certain speed. Once it has reached that speed, the object retains that amount of kinetic energy until that energy … WebPower is the measure of how much work can be done in a given amount of time. Mechanical power is commonly measured (in America) in “horsepower.” Electrical power is almost always measured in “watts,” and it can be calculated by the formula P = IE. Electrical power is a product of both voltage and current, not either one separately.
