The power factor always lies in a closed interval of -1 to +1. The power factor calculation can be done using a power triangle, the cosine of the angle between active power and apparent power is considered as power factor and it is same as the angle betweensupply voltageand load current....

If I know its electrical resistance is 0.72 x 10-6 Ω.m and I figure out the object's mass, how can I calculate the wattage required to bring that stainless steel bar to a specific temperature? All I have been able to find so far are formulas for heating wire. It seems ...

Earnings Power Value (EPV) is a method used to estimate the intrinsic value of a stock under the implicit assumption that the current earnings and cost of capital are sustainable. Table of Contents How Does the Earnings Power Value Work (EPV) How to Calculate Earnings Power Value (EPV) How...
How to Calculate Return on Incremental Invested Capital (ROIIC) The return on incremental invested capital (ROIIC), or “incremental return on invested capital”, is the ratio between the change in NOPAT over the course of a given period and the invested capital from the preceding period. In...
uses: This is based on the power of electrical equipment (kW or kVA) to calculate the current (ANN) formula. The size of the current is directly related to power and voltage, phase, power (also known as power factor and so on). Generally there are formulas for calculation, because ...
P= power,IorJ= Latin: influare, international ampere, or intensity andR= resistance. V= voltage, electric potential differenceΔ VorE= electromotive force (emf = voltage). Enter any two known values and press "calculate" to solve for the two others. Please, enter only two values. ...
It could of course be a giant on a cycle, but let's say it is driven by water/wind/manpower. Maybe I need to turn things around to be able to calculate what force is necessary to provide a given resistance (generator) with the given specs. My first toughs are that if t...
