NCERT Notes for Class 12 Physics: Points to Remember

We have provided some very important points from 12th NCERT Physics for students to refer to.

• There are two types of charges in nature; positive charge and negative charge. Like charges repel each other and unlike charges attract each other.

• In conductors, electric current is due to the movement of electrons through them, in insulators, electric current cannot flow.

• (i) Coulomb’s Law: The mutual electrostatic force between two point charges q1 and q2 is proportional to the product q1q2 and inversely proportional to the square of the distance r21 separating them.

• There are two poles; the north pole and the south pole. Like magnetic poles repel and unlike ones attract.

• Magnetic monopoles do not exist. If you slice a magnet in half, you get two smaller magnets.

• The average power loss over a complete cycle is given by P=VI cosϕ. The term cosϕ is called the power factor.

• Maxwell found an inconsistency in Ampere’s law and suggested the existence of an additional current, called displacement current.

• Metals have low resistivity (10−2 to 10−8 Ω m)

• Insulators have very high resistivity (1011Ω m−1 to 1019Ω m−1)

• Reflection is governed by the equation ∠i=∠r. Angles of incidence and reflection are i and r, respectively.

• The incident ray, reflected ray, and normal lie in the same plane.

• The phenomenon of refraction of light could not be explained by the corpuscular model of light proposed by Newton, but it was successfully explained by the wave nature of light proposed by Huygens.
