A conducting sphere has a total charge of 2 coulombs. What is the electric potential at a distance of 3 meters from the sphere, assuming that this is greater than the sphere's radius? What is drag force? What are the units of impulse?
The electromotive force or EMF is the electric force produced by the conversion of any form of energy into electric energy. The EMF is a quantity that is present in the explanations of the behavior of electrochemical cells and electromagnetic induction. For example, in the case of a simple el...
The proposed design scheme utilized a fan to force air circulation up along the side of modules where each module consists of four cells connected in series. A proposed feedback control loop system allowed for active control of the battery cell's temperature resulting in an increase in ...
The electric field between plates is the area or space where the plates' charges influences can be seen. For example, if a charged particle is placed near any charged plate, the plate exerts an electric force to attract or repel the charged particle. How to find the electric field between...
This concept can be confusing when first introduced. Looking at the formula for Coulomb’s Law below can help you visualize the relationship between charge and distance, and how this influences the electrostatic force (electrostatic force is the electric force between charged bodies at rest. This ...

My theory of electrical forces is that they are called into play in insulating media by slight electric displacements, which put certain small portions of the medium into a state of distortion which, being resisted by the elasticity of the medium, produces an electromotive force ... I suppose ...
To know what is electric potential recall that the electric field influences any charge placed in it by exerting an electric force F=q*E. But electric potential energy, or work that is needed to move the charge for a distance of r, is W=F*r. Substituting equations give: V=Wq=F∗rq...
