The basic components of electronics
The first question one will need to answer is- What is an electric circuit? A circuit, in simplest term, is a loop like structure that controls and directs currents of electricity in order to perform some functions. The name resounds of something which is closed. This ultimately leads one to another important question, which is – what is an electric current? The word current refers to anything that is in a flowing mode and this is referring to a flow of electric charge. Now that we know it is a flow of electric charges, then let us look up to answer the basic entity of an electric circuit- What is charge?
Understanding charge and its attributes
Let us try to answer what charge is. It is, in the language of physics, known as electric charge, electrical charge or electrostatic charge and the symbol that is used for it is q. The concept is expressed with the unit of matter that demonstrates the extent to which electrons are more or lesser than protons. Some experimental observations and simple assumptions are useful in explaining electrical phenomena. If one wishes to understand currents, radio waves and electronics separately, it is essential that the postulates are clearly stated and understood.
Just like everything has a measurement of it, in the same way charge is measured in units of Coulombs, which is shortened to C, which has been named in the honour of Charles Augustin Coulomb. He was the first pioneer of electric charge, after having measured force between charged objects. Talking about the attributes of electric charge, it is of two kinds, or styles as some might put it. Positive charge (+) and Negative charge (-). There are also variations in the measurement and those come under the study of the discrete nature of charge. What is important for one to know is that a Coulomb of charge is a lot of charge in total.
