                                                       NETRUAL WIRE

 In terms of a home’s power flow, the neutral wire provides a return path for currents essential to most modern U.S. electrical codes. Combined with a power source and ground wire, you have the makeup of a contemporary light switch, but earlier switches operate without the neutral. So when it comes to designing a smart home, a neutral wire can cause headaches if you don’t have one at your switch location. Or if you don’t know whether you have one, like me.

  What is Gauss Law? According to the Gauss law,  the total flux linked with a closed surface is 1/ε 0  times the charge enclosed by the closed surface. \oint{\vec{E}.\vec{d}s=\frac{1}{{{\in }_{0}}}q} ∮ E . d s = ∈ 0 ​ 1 ​ q  . For example, a point charge q is placed inside a cube of edge ‘a’. Now as per  Gauss law , the flux through each face of the cube is q/6ε 0 . The electric field is the basic concept to know about electricity. Generally, the electric field of the surface is calculated by applying  Coulomb’s law , but to calculate the electric field distribution in a closed surface, we need to understand the concept of Gauss law. It explains the electric charge enclosed in a closed or the electric charge present in the enclosed closed surface. Gauss Law Formula As per the Gauss theorem, the total charge enclosed in a closed surface is proportional to the total flux enclosed by the surface. Therefore, if ϕ is total flux and ϵ 0  is electr...

  Current Density Current Definition: We can define current as the flow of electrically charged particles, mostly in those atoms which are electron-deficient. The standard symbol of current is capital  I . The standard unit of current is ampere and it is denoted by  A . Conversely, a current of one ampere is one coulomb of charge(6.24 x 10 18  charge carriers) going past a given point per second. According to Physicists, Current is considered to move from relatively positive to negative points, and this is known as conventional current. Electrons are known to be the common negatively-charged carriers and circulate from relatively negative to positive points. In this article, we will learn about the concepts of Current Density in a detailed manner. Types of Current The current can be divided into two types. Direct Current: Direct current travels towards the same direction at all points, although the instantaneous magnitude can differ. An example of...
