Dear Friends, welcome back after a long interval of time. The topic of today is the aspects of electronics in terms of some basic elementary laws and some facts of it.
Electrical Circuits:
It can be defined as the systematic arrangement of basic components like R, L,C.
Basically the term electronics is totally dependent on the electromagnetic theory. Now question arises 'What actually mean by electromagnetic theory?'
Ans. Electromagnetic theory includes study of electric and magnetic fields, in which study from point charges to cloud of charges is included. This section includes electrostatic forces.
Okay, let's come back to the main topic. The purpose of mentioning of the electromagnetic theory is to introduce the concept of electric current and electric potential difference.
Voltage : As the concept of electric potential tells us, that a potential on a point charge like electron or a proton due to an electric field. Now assume that a charge moves from one point to other point (let's say initial position r1 to final position r2 ). Now obviously there may be two different potentials at these two positions , so, in other words we can say that there is an energy which is gained by that point charge. The gain in energy is given by,
amount of energy gained by that particle = q*( V1 - V2 ).
In other words, 1 joule of energy is obtained when a point charge of 1 coulomb is moved from one position to other position where the potential difference is 1V. Obviously this definition will like little bit tedious. In terms of equation I can represent as,
(1C)*(1V)= (1J).
or,
(1J)/(1C) = (1V).
Current : It can be represented in terms of the charge flowing through the point in presence of an electric field. But the current in terms of electric field will like some tedious equation. So the current is represented in terms of voltage (potential difference between two points due to electric field).
So, current is rate of flow of charge through a given surface like a conductor.
d(q)/dt = I.
Dear friends, all of us we know the importance of electronics in our day to day life. In the next post I will introduce more interesting topic. Wish you have a great day.
