Introduction Poisson distributions are frequently used to comprehend various events that take place continuously over a predetermined period of time. The Poisson distribution is a discrete function , therefore the variable can only take values from a list of (possibly infinite) numbers. The Poisson distribution is used in probability and ...

Introduction Sampling techniques refer to the different sampling techniques used to collect different types of samples in statistics. If you need to make statistical inferences about a population, it is almost impossible to collect data from all the units that belong to that group. In these situations, various sampling methods ...

Introduction The term Reciprocal means inversely related. In fraction, the term Reciprocal is taking the inverse, that is the place of numerator and denominator exchanges with each other. To check the Reciprocal value is taken the correct, invert and multiply that inverted number with the original number always equal to ... Read More

Introduction Division is the basic arithmetical operation in mathematics. It is the process of distributing things into equal parts. When the dividend is not completely divisible by the divisor it left a number or the value is known as the remainder. In mathematics, in numerous instances, the leftover part or ... Read More

Introduction In any business or research activity, a large number of data is produced, which becomes difficult to analyse. In this direction, a statistical process, sampling, is useful to analyse the entire population. However, in doing so, some error arises due to various reasons. For accurate data analysis, one must ... Read More

Introduction Diffusion and concentration process are fascinating phenomenon in the science field. It is a visible process in the physical world. The study of diffusion processes started in the 19th century. The spreading of the fragrance of flowers is the best-known example of this process. This process involves the ... Read More

Introduction Diffusion rate shows how fast the process of diffusion take place. The net migration of particles from a region of high concentration to one of low concentration is referred to as diffusion, which is a physical phenomenon. Diffusing substances might be solids, liquids, or gases. Similar to this, ... Read More

Introduction Dimension of area place an important role in the measurement process. Measurement is the most valuable part of science. Also, it is most important for living too. Measurement plays a crucial role in our lives. It is the foundation for all technological development. The accuracy of measurement is more ... Read More

Introduction Direct current generator produces electric current by the process of electromagnetic induction. The electromagnetic force gives rise to the electromagnetic field. In an electromagnetic field, the electric field and the magnetic field are intertwined. Electromagnetic force determines electromagnetic phenomena. Electromagnetic force is the interaction between charged particles. Lorentz's force ... Read More

Introduction Electric circuit and electrical symbols are important to understand to design any electrical or electronic instrument. The branch of physics that deals with the behavior of electrons using electronic circuits are called electronics. The components used in the electronic circuits are active devices and this is the difference between ... Read More
