it is given kinetic energy. The process is analogous to an object being accelerated by a 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...
Find the potential V both inside and outside the sphere. Solution: The electric field outside of the sphere is provided: V(r)=\frac{k Q}{r} so we should be focusing on dealing the electric field inside the sphere: d V=-\vec{\boldsymbol{E}} \cdot d \vec{\ell}=-\frac{k Q ...

The δ symbol vanishes unless its indices are the same. The summations occur over all charged particles in the molecule, both electrons and nuclei: qi represents the charge of the ith particle and ri denotes its position with respect to the center of mass of the molecule. Furthermore, Θα...
ohm: in the International System of Units, the derived unit of electrical resistance; the electrical resistance of a device across which a potential difference of one volt causes a current of one ampere; symbol: Ω ampere: A unit of electrical current; the standard base unit in the Internation...
The standard symbol used to represent charge is q or Q. Two particles (or objects) with the same type of charge repel each other, and two objects with the opposite types of charge attract each other. The charge is measured in units of coulomb, denoted by C. Electric potential/voltage ...
kilowatt-hour: a unit of electrical energy equal to that done by one kilowatt acting for one hour; equal to 3.6 mega-joules. Symbol: kWh.In many cases it is necessary to calculate the energy usage by an electric device or a collection of devices, such as in a home. For example, we ...
