Understand the concept of electric potential difference with an example, and learn how to find the electric potential difference formula between...
The potential of point A with respect to point B is defined as the work done in moving a per unit charge from point A to B in the presence of electric field E. Mathematically, this can be expressed as, This is also a potential difference between points A and B with point B as a ...

Potential Energy Equations If you lift amassmbyhmeters, its potential energy will bemgh, wheregis the acceleration due to gravity: PE = mgh. For a spring, potential energy is calculated based onHooke's Law, where the force is proportional to the length of stretch or compression (x) and ...
Other methods of predicting long-term returns—such as theMonte Carlo simulation, which usesprobability distributionsto determine the likelihood of different potential outcomes—have seen increasing popularity. Exponential growth models are more useful to predict investment returns when the rate of growth ...
A 1 farad capacitor, when charged with 1 coulomb ofelectrical charge, has apotential differenceof 1 volt between its plates. Types of Capacitors There are several types of capacitors for different applications and functions. Following are the Main and Most Common Types: ...
**An electron volt (eV) is NOT a unit of potential!** It is a unit of energy equivalent to the work done in accelerating an electron through a 1 volt potential difference. 1 electron volt = _e_ ×1 volt, where _e_ is the fundamental charge. ...
Formula and Calculation of the Information Ratio (IR) Although compared funds may be different in nature, the IR standardizes the returns by dividing the difference in their performances, known as their expectedactive return, by their tracking error: ...
While a bit complex mathematically, Bayes’ theorem is quite logical. If an investor discovers new economic information relevant to potential market returns, it makes sense to integrate this data to get a more precise calculation. The 18th-century English minister Thomas Bayes devised this statistical...
