CBSE Class 12 Physics Syllabus Overview

Electric charge resides on the surface of conductors

Gauss's law states that the total electric flux through a closed surface is equal to the charge enclosed by the surface divided by the permittivity of free space

The presence of a dielectric material between the plates of a capacitor increases the capacitance.

<p>Ohm's law states that the current passing through a conductor is directly proportional to the voltage applied across it, given a constant temperature.</p> Signup and view all the answers
