Electric Charges and Fields
Your child will build electrostatics from charge itself all the way to Gauss law. Electric charges together with potential generally command about sixteen marks jointly, the heaviest Class 12 physics block. Learners begin with charge conservation and quantisation, build Coulomb law for point charges with the superposition principle, develop the electric field idea with field lines and dipole fields, introduce electric flux, and arrive at Gauss law applied to the infinite line charge, the plane sheet and the spherical shell, closing by comparing electrostatic force with gravity.
