Electrostatics and Electricity

Electrostatics and Electricity

Electrostatics and Electricity for all type of students beginner to advance
Electrostatics is a branch of physics that deals with the electric charges at rest electric charges.

Since classical physics, it has been known that some materials such as amber attract lightweight particles after rubbing. The Greek word for amber, ήλεκτρΠν, or electron, was the source of the word 'electricity'. Electrostatic phenomena arise from the forces that electric charges exert on each other. Such forces are described by Coulomb's law. Even though electrostatically induced forces seem to be rather weak, some electrostatic forces such as the one between an electron and a proton, that together make up a hydrogen atom, is about 36 orders of magnitude stronger than the gravitational force acting between them.

Electricity is the set of physical phenomena associated with the presence of electric charge. Although initially considered a phenomenon separate from magnetism, since the development of Maxwell's Equations, both are recognized as part of a single phenomenon: electromagnetism. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. In addition, electricity is at the heart of many modern technologies.

The presence of an electric charge, which can be either positive or negative, produces an electric field. On the other hand, the movement of electric charges, which is known as electric current, produces a magnetic field.

Under Electrostatics module we tried to add almost all topics of static electricity, such as electric charges,
properties of electric charges
coulomb’s law
electric field
electric field strength
electric field at various point charges
principle of superposition
electric lines of forces
electric dipole
electric field due to electric dipole
torque on dipole
electrostatic potential
gauss’s law and its applications
conductors and insulators
capacitance
capacitors and combination of capacitors and energy stored in the capacitors.

Second module Current Electricity covers topics like
electric current
current density
drift velocity and its calculations
Ohm’s law
electrical resistivity and conductivity
carbon resistors and color coding
combination of resistors
temperature dependence of resistance
kirchhoff’s law
wheatstone’s bridge and determination of specific resistance and temperature coefficient of resistance.


Both modules in this application almost covers all about electrostatics and current electricity.
Students can easily learn each every topic with the help of pictures and simple mathematical expressions….Very helpful tutorials for students..
