Units and Dimensions

Each and every physical quantity known until day can be expressed in terms of seven fundamental quantities by calculations and relationships by using units and dimensions in physics. Units can be defined as the standard amount of a quantity for measuring physical quantities. Since there are many types of measurable quantities, there are many types […]

Understanding Alpha Rays

Alpha particles are also known as alpha radiations and alpha rays. The composition of alpha particles is similar to the composition of the helium-4 nucleus. The composition of alpha particles consists of a systematic arrangement of two neutrons and two protons. The study of alpha particles comes under Bosonic statistics. Alpha particles are considered highly

Types Of Temperature Coefficient Of Resistance

The variation in electrical resistance of a component with regard to each degree change in temperature is known as the temperature coefficient of resistance. When we consider the electrical resistance of a conductor be it gold, silver, copper and aluminium, we must consider the process of electron collision within the substance. The action of electron collision occurs

Types Of Semiconductors

A semiconductor is a material, normally a good complex ion or compound, that can carry current under certain circumstances but not others, making it an ideal form of expression for controlling the flow of electrical current. In terms of electrical conductivity, a semiconductor is a type of solid material that falls halfway between a conductor
