Electric charge is normally thought of in electrostatics as existing at certain locations, such as protons or electrons. However, charge is dispersed across an object. Protons What is Continuous Charge Distribution? An item is said to have a continuous charge distribution when its electric charge is dispersed evenly throughout it rather than concentrated at one … Read more
A dipole refers to a pair of equal and opposite charges (+q and -q) separated by a small distance (2a). The dipole is characterised by a quantity called the electric dipole moment (p). It is a vector quantity defined as: p = q × 2a The direction of dipole moment is from negative charge to … Read more
A dipole consists of two equal and opposite charges (+q and -q) separated by a small distance 2a. The dipole moment (p) is a vector quantity given by: p = q × 2a The direction of the dipole moment is from the negative charge to the positive charge. Positive charge Dipole in a Uniform External … Read more
An electric dipole is one of the simplest arrangements in electrostatics. It consists of two equal and opposite electric charges placed at a small distance from each other. Though small and simple, dipoles are very important in understanding how electric fields behave, especially in molecules and materials. Molecules A electric dipole is a system formed … Read more
Electric flux linked with a surface the number of electric lines of force cutting through a surface and measured as surface integral of electric field over that surface. Electric field What is Electric Flux? Electric flux can be thought of as the quantity of electric field lines that flow through a specific surface. Suppose, holding … Read more
We use electricity on a daily basis for everything from our smartphones to the lights in our houses. However, what goes on behind the scenes? Smartphones We enter the interesting dominion of electric fields when we discuss the charges and forces that exist between them. And we employ electric field lines, a useful instrument, to … Read more
We have all come across the impacts of electricity in our daily lives, from the spark that appears when we touch a doorknob to the operation of our cell phones. An unseen force known as the electric field is responsible for these events. What is an Electric Field? An area surrounding a charged object where … Read more
Electric interactions in electrostatics is the study of forces between numerous charges. When there are several point charges present, each one applies an electric force to the others, and the sum of the effects of all these separate forces determines the total force acting on any given charge. Coulomb’s Law We should review Coulomb’s Law. … Read more
Electric charge is one of the most fundamental properties in nature. It is responsible for all electric and magnetic phenomena. Magnetic phenomena Basic Properties of Electric Charge Two Types of Charges There are exactly two types of electric charges: Positive charge (like on a glass rod rubbed with silk) Negative charge (like on an ebonite … Read more
An interesting way to electrically charge an object without making direct contact is by induction charging. It is based on the idea that surrounding charged objects have the power to redistribute electric charges within a conductor. This idea is fundamental to understanding how electric fields behave and is used extensively in devices like touch screens, … Read more
