Class 12 Physics Formula Sheet PDF CBSE: Chapter-wise Quick Revision Guide

Quick Revision: Class 12 Physics Formulas

Class 12 Physics is divided between theory derivations and complex numericals. To score 95%+ in your CBSE board exams, having all formulas at your fingertips is essential. This quick revision sheet covers the critical equations from Electrostatics to Modern Physics.

1. Key Equations Chapter-Wise

• Electrostatics:
  Coulomb's Law: F = q1*q2 / (4 * pi * epsilon_0 * r^2)
  Gauss's Law: Phi = Q_enclosed / epsilon_0
  Capacitance: C = epsilon_0 * A / d (Parallel plate)
• Current Electricity:
  Ohm's Law: V = I * R
  Drift Velocity: v_d = e * E * tau / m
  Wheatstone Bridge: P/Q = R/S
• Optics:
  Mirror Formula: 1/f = 1/v + 1/u
  Lens Maker's Formula: 1/f = (n - 1) * (1/R1 - 1/R2)
• Modern Physics:
  Einstein's Photoelectric Equation: K_max = h * nu - phi_0
  De Broglie Wavelength: lambda = h / p = h / (m * v)
