Class X: Electricity and Magnetism in ONE diagram

This simple diagram will help you to remember two chapter namely Electricity and Second Magnetism and its Properties in a snapshot.


The Physics paper for Class 12 this will have a total of 26 Questions having a total of 70 Marks broken into to 5 Sections.

The questions will be of 1 mark, 2 marks, 3 marks, 4 marks and 5 marks each. If you have handle the Section C having 12 questions of 3 marks each, then you will surely score upward of and easy 55 marks this year in the Board Exam.

Electric Generator

An electric generator is a device where mechanical energy is used to rotate a conductor in a magnetic field to produce electricity…[…]

Electro-Magnetic Induction [ EMI ]

Induction means to create. Electromagnetic induction means to create electricity. Logically if electricity can create magnetic effect or magnetism, then by reverse analogy by using magnetism we can electricity. It’s true, first thought by Sir Michael Faraday…[…]

Electric Motor

An electric motor is a rotating device that converts electrical energy to mechanical energy. An electric motor is used as an important component in electric fans, refrigerators, mixers, washing machines, computers etc…[…]

Magnets and Magnetic Fields

A magnet is a piece of iron or other material which exhibits properties of magnetism, such as attracting other iron-containing objects or aligning itself in an external magnetic field…[…]

Electricity – Heating Effects

We all know that current heats when it passes through a wire.  We want to find out why current heats the wire and what is the amount of heat generated…[…]

Electricity – Combination of Resistors

Now that you know what resistors are, now find out more how they can be combined in this blog post…[…]

Electricity – Ohm’s Law and Resistivity

The electric current flowing through a metallic wire is directly proportional to the potential difference V, across its ends provided its temperature remains the same…[…]

Scattering of Light

Scattering of Light can be thought of as the deflection of a ray of light from a straight path by irregularities or non-uniformities in the propagation medium, through which it passes…[…]

Atmospheric Refraction

Atmospheric Refraction gives rise to many natural phenomenons. Learn more about such natural phenomenon and what causes them…[…]

Dispersion of Light

A prism is a transparent optical element where two of the flat surfaces have an angle between them for refraction of light…[…]

Defects of Vision

Human Eye, due to wear and tear or due to accidents develops defects. These defects are called defects of vision…[…]

Light – Lens Formula and Power of a Lens

Lens formula is similar to Mirror formula except that the +ve sign is replaced by -ve sign.  The power of a Lens is the power on our spectacles…[…]

Light – Refraction by Convex Lens

Just remember Convex Lens is similar to Concave Mirror.  The rest of the things are just similar…[…]

Light – Refraction by Concave Lens

You will learn more about refraction by Concave Lenses. Just remember the properties of Concave Lens is similar to Convex Mirror…[…]

Refraction & Refractive Index

Refraction is an important phenomenon exhibited by light when it travel from one medium to another.  One of the ways to measure refraction is the refractive index…[…]
