Electric current-classification
The electricity flow from one place to another place with respect to time said as electric current. According to its nature of flow through a medium, it can be classified into two categories,
Fundamental
Resistors in Parallel Circuit
o connect resistors in parallel connection one end of the all resistors connected together as same as another end of those resistors are connected together. A source connected between these both junction to deliver current to it. In figure R1, R2,R3 resistors one end (A) connected which further connected with positive terminal of the source.
Resistor in Series Circuit
Resistors are used in circuit as load or control voltage and current though a path. To do those resistors are connected in various method such series, parallel, series-parallel combination. Series circuit combination used where low voltage loads or connected , So certain voltage can be dropped in series resistors.
Various Atomic Models
Since, earlier years various type of atomic models are demonstrated by scientist according to their experiment in atomic physics, Let see about that various model of atomic structure here.
Atom an Introduction
Atom is a Greek word which means “it is indivisible further”. Universe made with variety kind of atom in nature. Atom is a smallest particle exists in every element. According to combination of elements it creates different kind of material depending on physical and chemical properties of an Atom.
Specific Resistance
As we know that resistance is a property which oppose to flow electric current through a material. But it is important to note that each material does not offer same value of resistance to flow of electricity. Definitely it differs from one material to another material.
Ohms Law
Ohms Law says Current flowing through an electrical circuit is directly proportional to applied voltage and inversely proportional to the resistance offered by the circuit while ambient temperature and other conditions are remains constant.
Types of Electrical Networks
An Electrical network which formed using multiple kind of elements such electrical source, control switches, loads, transmission medium. A electrical network made for purpose of transmit and consume electrical energy which generated from source to load. It does not matter that every network must contain all type of elements. It is required to develop a network to perform their function accordingly.
What is Electricity
Electricity is a phenomenon which exists in nature. The universe each material made by various type of atoms. property of these material depends upon kind of atom found in it. According to these are dived into solid , liquid and gases etc.
