Sometimes electrical potential energy is called merely electrical energy. There are two ways to consider electrical potential. (1) From the action-at-a-distance viewpoint, the electrical potential is obtained as a sum of the contributions from every electric charge, with the potential at infinity ...
In a system and method for converting potential energy into electrical energy, a force is applied to a force receiving end of a pendulum arm of a pendulum. The pendulum arm is connected to a periphery of a wheel. The wheel is rotated using the force applied through the pendulum arm and ...

In Electric Charge and Electric Field, we just scratched the surface (or at least rubbed it) of electrical phenomena. Two of the most familiar aspects of electricity are its energy and voltage. We know, for example, that great amounts of electrical energy can be stored in batteries, are tr...
之前说了有关电场力的一些内容,这一节自然而然我们会想研究有关功,能量的问题,作为一种守恒量,研究做功和能量显然是分析实际问题中非常有效率和意义的事情。后面我们会看到,电场力实际上是一种保守力(conservative),也就是能量变化或做功的多少并不和受力物体的实际运动轨迹有关,只和起始位置和终点位置有关,因此...
gravitational field. It is as if the charge is going down an electrical hill where its electric potential energy is converted to kinetic energy. Let us explore the work done on a chargeqby the electric field in this process, so that we may develop a definition of electric potential energy....
Potential energyis present in an object that is affected by a force field. One example is water in ahydropower plant. Calculations of potential energy are made according to the following formula (2.2)E=m·g·h whereEis the energy (J);mis the mass (kg);gis the gravity acceleration (m/s2...

The electric potential energy Uel of a given configuration of charges is equal to the work (by an external agent) required to assemble the configuration. Because the work that must be done against electrical forces to bring a point charge Q from an infinite separation to a point where the ...
