Electric current

A brief introduction of Electric Current, and its definition, explaining the unit of the same, various effects of Electric Current and conventional Current

Introduction

The Electric Current is a topic that holds various aspects of physics and describes the current flow and usage that we usually see in our daily lives. The study shows multiple uses of Electric Current and the definition to understand it clearly. Also, in this particular topic, other things include the Defining Electric Current and the Visualizing Electric Current. 

Definition:

The stream of charged particles can be used to define Electric Current. This stream of charges can further include ions and electrons which flow through the electrical conductor. Well, the conductor is the object or type of material that helps flow the energy from one direction to the opposite direction. However, the good conductors of heat and electricity can only allow this performance.

Defining Electric Current

The stream of charged particles that passes through a good conductor is known as the Electric Current. Like: electrons – containing negative charge, protons containing positive charge, holes – insufficiency of electrons that can be turned into atoms, and ions – these are the atoms that have already lost or gained electrons. 

Electric Current Unit

The unit of charge is denoted with the help of Coulomb that can also be represented as C. Normally, the conductors or any materials are made up of positively charged Nuclei, along with the negatively charged electrons. However, the negatively charged electron surrounds the positive nuclei. 

This can be further denoted as:

Proton charge  e+ = 1.602 10-19 coulombs

Electron charge  e- = -1.602 10-19 coulombs

Thus, the force created among the positive and negative charges is characterized and acknowledged by the electrical field formed with the help of voltage. Also, light bulbs usually contain 120 watts, from where 1 C of Electric Current is passed in one second.

The SI Unit of Electric Current is denoted with the help of the Ampere or amp and is also visualized with the help of the A. It can also be stated that the Ampere is the central basic Unit of the Electric Current. Furthermore, the term Ampere further was invented with the help of Andrew Marie Ampere. Thus, if you witness a circuit, you will see that the amount of Electric Current is similar to the rate of the Coulomb per second.

Thus, it can be found from the above explanation that: 1 Ampere=1 Coulomb/1 Second = C/S.

Furthermore, the Unit of Electric Current is quite similar to the current and electricity. 

Commonly, the Electric Current is denoted with the symbol called I, which is why the Electric Current Unit is considered I, but according to Ohm’s Law. Thus, Ohm’s Law Defining Electric Current, which passes from a good conductor, contains a Voltage V along with the resistance called R. This is further denoted as V=IR.

From the above statement, the Electric Current Unit is I = V/R. 

The Electric Current present in a wire holds the electrons, which can be further measured with the quantity of electricity going through points of the wire per unit of time. 

Visualizing Electric Current 

The Visualizing Electric Current can be performed with the conductor and the Electric Current. Therefore, the Visualizing Electric Current is nothing but the amount of charge that flows from the objects. To understand this in the best way, you can further think of the electricity and Water Pipe analogy or consider the Water analogy of electricity. However, it holds some amount of restrictions as well.  

In the Water Analogy of Electricity, you have to differentiate between the water passing through the pipe and the Electric Current. These will further help you to understand the Visualizing Electric Current. Also, in this process, you will notice that when the one end of the pipe is enjoying the pressure, the water starts flowing in one direction. Similarly, the amount of water flow is directly proportional to the pressure applied on one end. This pressure can also be defined as the Electromotive Force.

Various Effects of Electric Current

The Electric Current can serve many effects that are further listed below. However, the consequences can additionally depend on the amount of electricity passing through the conductor. 

  • Magnetic Effect: One of the most pronounced effects of the Electric Current is the magnetic effect. This is also highly noticeable whenever the current passes through the conductor, creating the magnetic field. For instance, keep a compass near the wire with a considerable amount of Current flowing through it. You will further notice that the compass will deflect. Also, these magnetic fields created by the same can be used for several other good reasons, like winding a wire into a coil. These are pretty common, and you will often see the electromagnet increased to serve many different purposes.
  • Heating Effect: The heating effect produced by the flow of electric Current can be denoted as H=I²RT, and these are commonly witnessed in our daily lives. For instance, you have seen the use of geysers, iron, and numerous things. In these things, the electric Current produces heat that helps to give relief from many things. Also, when a conductor witnesses the electric Current, it automatically produces heat energy.

Conventional Current Flow

The conventional Current flow flows the Current from positive to negative terminals. On the other hand, the electron flows from the negative to the positive terminal. 

Conclusion:

In this article we give a brief overview of electric current. Electric current is defined as the rate of charge flow and its SI unit is ampere,  which is equivalent to coulomb per second. We also explained some effects of electric current such as magnetic effect and heat effect. Magnetic field is induced in conductors due to current.
