An electric charge can be both positive or negative. If two objects have opposite charges, they will attract each other and if two objects have the same charge, they will repel each other. An electric charge has coulomb as a unit. It shows the amount of electricity carried by an electric current of 1 ampere […]

The electric charge is all about us, and there is plenty of evidence to back this up. Have you ever lifted a comb to your hair after rubbing it through a towel? That section of your hair will be pulled to the comb. This is primarily concerned with the generation of electrical charge. In this

If a charged particle moves through an electric field, it experiences an electric force. This force can be one of attraction or repulsion, depending on the particle’s charge.   The magnitude of the electric force on a moving charge in an electric field is equal to the product of the electric field and the charge of

Electric flux is the measure of an electric field or it is the method of describing the electric field strength at a specific distance from the causative charge of the field. It can also be thought of as the number of electric field lines intersecting at a given area. These field lines originate on the positive

The electric push working in an electric field on a unit charge at some point is called electric field intensity. It is a vector quantity with both direction and magnitude. On the other hand, the electrical situation for which a flow of charge takes place in two charged bodies is called electric potential-the work quantity

Electric current cannot readily travel through an electrical insulator. The electrons in the insulator’s atoms are closely bonded and unable to flow freely. Semiconductors and conductors, for example, are better at conducting electric current. Insulators have a higher resistance than semiconductors or conductors, which is what separates them. Non-metallics are the most prevalent example. Even

The foremost common examples are non-metals. An ideal insulator does not exist as a result of even insulators containing tiny numbers of mobile charges (charge carriers) which can carry current. In addition, all insulators become electrically semi conductive once a sufficiently massive voltage is applied that the electrical field tears electrons far from the atoms.

The word hydro relates to fluid, while the word static refers to something that is motionless. As a result, hydrostatics is a branch of fluid mechanics that studies the characteristics of a fluid at rest as well as the pressure produced by the fluid on an object immersed in it, among other things. This is

Two electrical charges, ‘+Q’ and ‘-Q’, when separated by a distance ‘d’ between them, form an electric dipole where the mid-point of +Q and -Q is known as the centre of the dipole. By default, the direction of an electric dipole is taken from the negative charge -Q to the positive charge ‘Q’. The electric

The concept of an electric dipole is pretty simple. The electric dipole is a pair of point charges equal in magnitude but carrying opposite charges separated by distance. +q and -q are point charges separated by a distance of 2x. The middle point of the charges +q and -q is the dipole’s centre.  The dipole
