In the year 1929-30, scientist Lawrence invented a particle accelerator device called the cyclotron. A cyclotron contains a hollow cylinder. This cylinder has two Dees in a vacuum chamber. An electric field accelerates the charged particles along a spiral path in this cylinder. Principle of Cyclotron The working principle of a cyclotron is that the […]

Generally Voltage of Hundreds of thousands of volts can be generated by the Van de Graff generator. Startling releases from the Van de Graff do not represent a serious shock risk as the currents attainable are so small. There is a pulley which pulls an insulating belt through a sharp pointed metal comb that provides

V-I characteristics represent an electrical component’s voltage-ampere characteristics. It is described in the form of a graph. The V-I chart provides information about the Resistance and the functional area of an element. Thus, the graph breaks down an electronic component. The study of V-I characteristics of a component helps us determine where and how to

Introduction We all know V-I characteristics as they represent the voltage and current characteristics. The V-I characteristics are used to know about the resistance and break down in electronic components and provide the operating region of a component. There are two types of V-I characteristics, i.e. linear and nonlinear. Ohm’s law exists for linear, but

When we hear the term dipole, the first definition that comes to our mind is that a pair of opposing charges q and –q separated by a distance d is called a dipole. This definition is somewhere correct, but there is also another definition. The separation of charges within a molecule between two covalently bound

Introduction: First, we need to understand what Electric Charge is. So, the physical property of a thing that causes it to experience an electric force is called an electric charge. It is represented by “q”. The unit of electric charge is “coulomb”. Electric Charges are of two types, i.e. Positive Charge and negative charge.  Now,

Meaning of electric field The area around the electric charge in which the electric force or stress would be exerted on other charged particles or objects is known as the electric field. It depends on the magnitude. If the magnitude of the charge is high, then it will create a huge amount of stress on

An electric dipole is a separation of opposite electrical charges. The electric dipole moment p is the product of any two charges multiplied by the distance between them. Its direction is from a negative to a positive charge. The axis of a dipole is the line that connects the two charges. Assume that the charges

Electric charge can be said to be the fundamental feature of matter. It controls how elementary particles are influenced by a magnetic field or an electric field. Electric charges can neither be created nor destroyed; they exist in discrete units. Two types of electric charges exist: positive and negative. Same charges repel each other, just

The superposition principle of electric charges is very similar to the superposition of waves. Force on a specific charge due to another charge under an electric field’s influence cannot be calculated as the scalar sum. On the other hand, It would be the excess of these forces that takes place. The most famous example of
