02062020 Dioptre formula is used to calculate the optical power of a lens or curved mirror.

Physics formula to calculate power. We can refer to power as the rate at which we do work. Power Formula 1 Electrical power equation. We can define energy as the strength to do any kind of physical activity.

I 2 V 2 R where power P is in watts voltage V is in volts and current I is in amperes DC. Tr 3862 Power Output Formula Power Output Formula. The dioptre is the unit for a measure of the refractive index of a lens.

Power unit of measure Watt W work done by the body t time. Time P. 28022020 The power is calculated in general terms according to the following formula.

Therefore we can say that Energy is the ability to do work. Electric energy P. P ΔE Δt ΔE represents the change of energy or the variation of work.

Mathematically it is computed using the following equation. Power is the rate at which work is done. Therefore it can be calculated by dividing work done by time.

Power fracworktime Or. The following formulas are used to calculate power. If there is AC look also at the power factor PF cos φ and φ power factor angle.

Physics plays a crucial role in our daily life. V R. The term of physics.

As is implied by the equation for power a unit of power is equivalent to a unit of work divided by a unit of time. It is the worktime ratio. Power is the rate at which work is done.

In this case determine the values of both F and v and use this to calculate the power. Power is how fast energy is used. Power of Lens Calculation.

Also it is the ratio of work and time. Just copy and paste the below code to your webpage where you want to display this calculator. Electric Energy The electric energy is defined as the total work done or energy supplied by the source of emf.

There are two ways to calculate power. Here we can calculate Power Work Time. Work done W.

In maintaining the current in an electric circuit for a given time. Here we can calculate Power Work Time. The power of a lens is specified as the inverse of the focal length in meters or D 1 F where D is the power in dioptres.

Electric energy electric power. P o w e r e n e r g y t i m e P Q V t where Q V is the electrical energy consumed by the load with potential difference V when Q charge passes through. 24012019 As discussed power is the rate of doing work.

In this article we will discuss the concept of energy and energy formula physics with. Besides we calculate it mathematically using this formula or equation. Power is defined as P F v where F is the driving force and v is the velocity of the moving object.

Energy is a very important concept in Physics. 21052020 Power Transported By String Wave. P Power dWdt where W is work and t is time.

T Thus the formula for electric energy is given by. Power is the rate at which electrical energy is supplied to a circuit or consumed by a load. Power Formula is articulated as latexP frac E t latex latexP frac W t latex or Where The Energy Consumed to do work E.

Power P I. The formula for power is given below. T V.

T V 2 t R. In this lesson we will go through the two equations for power and explain how they can be applied to physics scenarios. 19092010 Powerwork donetime interval in Newton meters per second or Watts WorkFd in Newton meters or Joules The Attempt at a Solution Power Fdt m a dt 50kg 98 ms2 12m15s 392 Nms 392 W.

Power Watt frac Wt Derivation of Power formula. In any electrical circuit the power is computed making use of these three formulas. Power Work time or P W t.

The standard metric unit of power is the Watt. Code to add this calci to your website. T I 2.
