Like resistors, a circuit can also have a combination of cells connected in series, parallel or even both! And again like resistors, we can calculate current and voltages that can be replaced by an equivalent cell in a circuit which we will learn here. A circuit composed solely of components connected in series is known as a series circuit; likewise, one connected completely in parallel is known as a parallel circuit. In a series circuit, the current that flows through each of the components is ...

Resistors are the most common and important component of any electronic circuit. In daily life we see a lot of circuits having resistances but how do we recognize them? To know the value of a resistance they are color coded with rings which have specific meanings according to the color and the place they are at. Let's figure out now what Resistance Color Code is and what it all means!! Contents: Resistance Color Code Wire Bound resistors Carbon Resistor Color Coding of Carbon Resistors Body End ...

We have learn now what a resistance it. Now let's see how the combination of resistances can be used in a circuit to control the flow of current and voltage division. Majorly the combination of these resistances are of 2 types: Series and Parallel. Here we will be taken both in detail below. Contents: Combination of Resistances Series Combination Parallel Combination Solved Examples Combination of Resistances A series circuit comprises a path along which the whole current flows through each comp...
Read More →Introduction to Ohm's Law and Resistance | Resistivity | Thermistors
We now have basic idea about Potential difference and Current. Now let us study the relation between them. How potential difference applied across the conductor and current flowing through it are related to each other if certain physical conditions are kept the same. This relation was given by G. S. Ohm in 1828 even before the physical mechanism responsible for flow of current was discovered. We will start with Introduction to Ohm's Law along with resistance, resistivity, specific uses of conduc...

In electrostatics, we studied charges at rest. In real life the most important application without which we can't think of our lives i.e. electricity is produced by charges in motion. Charges in motion constitute electric current. Here we will see the basic things like Unit of Electric Current, Types of Electric Current, Effects of Electric Current and Current density. Let's start: Introduction to Electric Current Unit of Electric Current Current Density Effects of Electric Current Types of Elec...
Read More →Gauss’s Law : Introduction | Electric Flux | Applications | Examples
Electric lines of Force are used to measure Electric Flux. It is a property of Electric Field which tells us the number of field lines crossing a particular area. It is rate of flow of electric field through a surface which can be open or closed. We will also discuss Gauss’s Law in detail which is an application of Electric Flux which helps to calculate Electric Field for a given charge distribution enclosed by a closed surface. We will study its application in detail here. Here you will get to ...

If we bring an electric charge into an electric field, how many places can we keep it? Infinitely many points, Right. As we know, it will experience a force which is different at different points. The problem is how can we represent the strength of the force at any point without calculating it mathematically, Michael Faraday came up with concept of imaginary lines, which are called as Electric lines of Force. They are also known as Electric Field Lines. Here you will get to know in detail about:...
Read More →What is Electric Potential & Potential difference?
As we know that electric charge forms an electric field around itself. But what if some other charge tries to come into that electric field? Is it that easy to enter into someone’s electric field? The answer is No. As the charge trying to enter also has an electric field. The amount of work needed to move a unit positive charge from one point to another (in the electric field of a charge) is called Electric Potential. The difference of Electric Potential between two points is called Potential di...
Read More →Electric Field Definition | Electric Field Intensity | Examples
As we have studied Coulomb’s Law, we know that charges either attract or repel each other even when they are a distance apart. Have you ever wondered why they experience such a force? It is somewhat like a Tiger. Every charge forms a territory around itself. If some other charge or charges comes in its territory then they experience a force according to their nature. This space a charge creates around itself is called as Electric field. So, here we are going to know more about Electric Field, it...
