This Revision Series is for all the aspirants, who are seeking for quick revision. eSaral has launched Physics Revision Series for all JEE & NEET aspirants. The main mission behind this series is to provide quick revision of all the chapters of Class 11th & 12th with important key concepts. As the limited time is left for all Exams weather you are preparing for Boards, JEE or NEET. This superfast revision series is launched to help all the aspirants of JEE and NEET and most helpful for all those who are going to appear in 12th Board. You can save your time here. Instead of going through chapter notes in detail, learn and revise most important key concepts from here.

Here is the Revision complete Current Electricity Chapter with important key concepts.

Electric Current, Drift Velocity, Ohm’s Law, Resistance and Resistors

Can you Imagine your life without electricity? Can’t Imagine, isn’t it? As we all know, that everything is working on electricity weather our cell phone, internet, computer, etc. Electricity plays a significant role in our life! Come to another point Is it possible to get an electric shock from a plastic wire? Yes you can never get electric shock from plastic wires. This is because of phenomenon called Resistivity that is discussed in detailed by Saransh Sir in this video. Let’s unravel more mysteries of electricity in this video with Saransh Sir. Get to know some other concepts also such as Drift Velocity, Ohm’s Law, Resistance and Resistors in this video.


Cells, EMF, Internal Resistance, Wheatstone Bridge, Potentiometer, Series and Parallel Combination

A complete circuit comprises of Cells, EMF, Internal Resistance. And all these components help in electricity flow within the circuit. An important part of electric circuits is Resistors. When a resistor connects to a combination of series and parallel connection it forms more complex circuit networks. Regulation of the current level of a device is a resistor’s functionality. In this video get to know more about resistors in series or parallel. Also study the experiments related to Wheatstone Bridge and the potentiometer which are among those things in science that raises sense of curiosity.


Power Delivered & Heat Dissipated

The heat dissipation inside a resistor is only the power dissipated across that resistor since power represents energy per time put into a system. Study in detailed by Saransh Gupta Sir in this Video.


Using Ammeter and Voltmeter in Circuit, Ammeter and Voltmeter construction

A voltmeter is an instrument used to measuring electrical potential difference between two points in an electric circuit. An ammeter is a measuring device used to measure the electric current in a circuit. A voltmeter is connected in parallel with a device to measure its voltage, while an ammeter is connected in series with a device to measure its current. Get to know in Detail by Saransh Gupta Sir in this Video.



Meter Bridge, Potentiometer, Post Office box.

As we can see that very frequently science presenting us with one or more ways to feel amazed. Lots of experiments shows both how we can exploit things and make innovative things out of them. Experiments associated to Wheatstone Bridge and the potentiometer are from few such things in science that raises a sense of Curiosity. Let us study in detail about the concept of Post Office box and Meter Bridge, along with Potentiometer by Saransh Gupta Sir in this Video.
