Syllabus and Exam Weightage for Class

It is important for students to know the Physics Class 12 weightage since there is a new pattern for the CBSE Class 12 Physics syllabus drafted by the board. Students are expected to study very effectively in order to ace in the topics which are included in the CBSE syllabus for Class 12 Physics. Apart from that, students need to make themselves aware of the new Class 12 Physics weightage to prepare better for the exams. Extramarks provides the best quality learning material for students to study the CBSE syllabus for Class 12 Physics. The study material provided by Extramarks is kept on par with Class 12 Physics weightage. Below are some of the topics that are included in the CBSE Class 12 Physics syllabus:
Chapter 1 Electric Charges and Fields 
Chapter 2 Electrostatic Potential and Capacitance 
Chapter 3 Current Electricity
Chapter 4 Moving Charges and Magnetism 
Chapter 5 Magnetism And Matter 
Magnetic Field Lines. These are imaginary lines that give an image of the magnetic field inside and around the magnet.
Their properties are given as follows: These lines form continuous closed loops.
(ii) The tangent to the field line indicates the direction of the field at that point.
(iii) The larger the width of the plates, the greater the magnetic field.
(iv) Both sections do not cross. The direction of the magnetic field between the poles of the dipole is in the direction opposite to the magnetic moment (South to North), while within the current circle it is in the same direction as that of the magnetic moment. The electrostatic potential is a state-dependent phenomenon since electrostatic forces are conservative forces.
Electrostatic Potential Difference. The electrostatic potential difference between two points in the electrical field is characterized as the amount of work accomplished by transferring the positive test unit from one point to the other against the electrostatic force without any acceleration (i.e. the difference between the electrostatic potentials of the two points in the electrical field).  The potential at a point due to a positive charge is positive while it is negative due to a negative charge.
When a positive charge is put in an electrical field, it encounters a force that pushes it from points of higher potential to points of lower potential. On the other hand, a negative charge experiences a force driving it from lower to a higher potential. 
Equipotential Surface. A surface with the same electrostatic potential at each point on it is known as the equipotential surface. The shape of the equipotential surface due to the line load is cylindrical.
