  2. Activities and Projects – These are designed to test a student’s ability to apply concepts in real-life situations.

Each experiment in the manual includes:

  • Aim of the experiment

  • Apparatus required

  • Theoretical background

  • Step-by-step procedure

  • Observations and calculations

  • Result and conclusion

  • Precautions and sources of error

This detailed structure helps students perform every activity systematically and gain conceptual clarity.

List of Common Class 12 Physics Experiments (As per CBSE)

The CBSE Physics practical syllabus for Class 12 includes experiments related to:

  • Resistors and Ohm’s Law

  • Potentiometer experiments to compare EMFs

  • Meter bridge for resistance measurement

  • Combination of lenses and mirrors for focal length determination

  • Verification of laws of reflection and refraction

  • Characteristics of PN junction diode and Zener diode
