today we charge the batteries of our mobile phones by directly connecting them to the socket but here's the problem if you were to directly take a couple of wires from the batteries and connect them directly to the socket and say close the switch then your phone will probably blow up because the world is that you get from here is very high you may have already learned it's about 200 volts but even if you could solve the problem of the voltage maybe we could somehow lower the voltage even then your battery will not get charged there's a very good chance your battery will just get spoiled and the reason for that is because the current that we get from the socket from the wall is an alternating current which means the charges are going to keep changing their direction of flow so once therefore maybe clockwise and then maybe they'll flow anti-clockwise and as a result when the current is flowing in one direction your battery might get charged but when it flows in the opposite direction will get discharged we get charged and then discharged and so your battery will not get recharged at all it might even get spoiled so in order to successfully charge the battery we need to do two things one is we need to lower the voltage that something will not focus on in this video but the second thing is we need to convert this alternating flow into a direct flow a one directional flow and that's what we will see in this video how to do that alright let's open the switch and our first step i...

A Project can help a student to understand the complex structure of the subjects in a minute or even seconds. Well-Structured projects and models explain so well and make it simple for the students to figure out the reasons behind the laws, derivations, equations etc. CBSE approached the interactive mean of the learning for the students. CBSE bestow the projects to the students to grab the knowledge of science and break the complexity. Students have to make the projects according to CBSE Syllabus guidelines of their elective subjects. Eduncle have picked the list of top CBSE projects for class 12 science stream students. Subject-wise List of CBSE Class 12 Projects Here, we have clubbed the CBSE projects for class 12 students who will opt science stream. Making a project is a compulsory part for the 12 as the marks will be addon with your result. Below is the subject-wise list of projects for science stream. Biology Mathematics Physics Project for CBSE Class 12 The study of properties and matter, energy and their mutual relationship are called Physics. The branch of Physics is mainly concerned with the law of motion and gravitation. Physics projects are the best way to understand the concepts behind the formulas and derivations. Preparing the working model help students understand the basic reasons. Newtons 3 rd law “every action has an equal and opposite reaction” is the best stated by playing with bat and ball. CBSE projects for class 12 Physics listed below: S.No. Projec...

FULL WAVE RECTIFIER: INTRODUCTION: Rectifier is a device which converts AC to DC. Now, it depends upon the percentage of rectification. There are 3 types of rectifiers: 1. 2. 3. Half-wave rectifier Full-wave rectifier Bridge rectifier A rectifier that rectifies only one half of each a.c. input supply cycle is called a half-wave rectifier. A rectifier that rectifies both halves of each a.c. input cycle is called a full-wave rectifier. It can convert a.c to d.c. approximately up to 85%. To make it 95% perfect I’ve used a electrolytic capacitor(470mfd) as it filters the current signal. Principle: It also works on the principle that a junction diode offers low resistance during forward bias and high resistance, when reversed biased. Here, two junction diodes are connected in such a manner that if one half cycle of a.c. input is forward biased, the other gets reversed biased but when the next opposite half cycle comes, the first diode gets reverse biased and the second forward biased. Thus, output is obtained during both the half cycle of the a.c. input. Working: Full wave rectifier is constructed by using a step-down transformer. When we input 220V a.c. cycle into the primary coil, due to the electromagnetic induction and also due to the reduced EDDY current, 220V is converted into 6V low a.c. cycle. I’ve connected diodes D1 and D2 which is the most important part of this circuit. During positive half cycle diode D1 is active as it is in forward biased condition while D2 is in...

Right from the very beginning, the concepts and theories of Physics are taught but it is only in Senior Secondary Education that a separate book is committed to Physics and is taught as a different subject. In CBSE, physics chapters of class 12th enclose a vast range of concepts and theories that reinforce and enhance a student’s understanding and knowledge of the subject. But being a practical oriented subject, it demands and requires practical work and project work at the end duration of the course. Skillset Students need to possess the following skills in order to carry out the physics project efficiently: 1) Problem Solving– Physics is a subject where a student may come across various challenges. This skill is required to go remove (or reduce) those hurdles. Possess...

Physics is an interesting subject that studies laws of nature, elements of the universe such as light, energy, force, etc. It is an Important Branch of Science and works on the principle of observation and experimentation. Physics Concepts are taught in Senior Secondary Education and it is taught as a separate subject. Physics Chapters include a broad range of concepts that enhances your level of understanding of the subject. Since Physics is a Practical Subject it demands more practical work and project work at the end of the course.
