Chapter 1: Electric Charges and Fields

Quantization of Electric Charge: The magnitude of all charges found in nature are in integral multiple of a fundamental charge. Q = ne, where, e is the fundamental unit of charge.

Chapter 2: Electrostatic Potential and Capacitance

Equipotential Surface: A surface on which electric potential is equal at all the points is called an equipotential surface. The direction of electric field is normal to the equipotential surface.

Chapter 3: Current Electricity

Potentiometer: It is a device in which one can obtain a continuously varying potential difference between any two points which can be measured simultaneously. The potential difference between any two points of a potentiometer wire is directly proportional to the distance between that two points.

Chapter 4: Moving Charges and Magnetism

Ampere’s Circuital Law: The line integral of magnetic field on a closed curve in a magnetic field, is equal to the product of the algebraic sum of the electric currents enclosed by that closed curve and the permeability of vacuum.

Chapter 5: Magnetism and Matter

The magnetic field lines do not intersect at a point. It forms continuous closed loops. It emerges out from the magnetic north pole, reach the magnetic south pole and then passing through the magnet reach to the north pole to complete the loop.

Chapter 6: Electromagnetic Induction

Self-Induction: When a current flowing through the coil is changed, the magnetic flux linked with the coil itself changes. In such circumstances, an emf is induced in the coil. Such emf is called self-induced emf and this phenomenon is called self-induction.

Chapter 7: Alternating Current

Step-up or Step-Down transformer: A.C. voltage can be increased or decreased with the help of the transformer. The transformer which increases A.C. voltage is called step-up transformer and the transformer which decreases AC voltage is called step-down transformer.
