Class 12 Physics Practical File

• To determine the resistance per unit length of a given wire by plotting a graph of Potential difference vs Current. • To determine resistance of a given wire using metre bridge& hence determine the specific resistance of the material. • To verify law of combination of resistance using metre bridge. • To compare EMF of two given Primary cells using a Potentiometer. • To determine the internal resistance of given primary cell using a Potentiometer. • To find the value of v(Image Distance) for different values of u(Object Distance) of a concave mirror & to find the focal length by plotting graph between u &v or 1/u & 1/v.

Physics file was the most difficult to maintain, all the reading and so much calculation. I thought in the day of my desolation when no one would share the file or they themselves have not completed it or maybe have done the whole practical wrong, interred a sense of Board Exam in my bones.

• To find the focal length of a convex lens by plotting graph between u &v or 1/u & 1/v. • To find the focal length of a Convex Mirror using Convex lens. • To find the focal length of a Concave lens using Convex lens. • To determine the angle of minimum deviation for a given glass prism by plotting a graph between the angle of incidence & the angle of deviation. • To draw the I-V Characteristic curve of a p-n junction diode in forward bias & reverse bias & to determine its static & dynamic resistance. • To draw the I-V Characteristic curve of the given Zener diode in reverse bias. • To study the characteristic of a Common Emitter npn or pnp transistor & to find out values of current & voltage gains.

Physics Practicals For Class 12 Physics is one of the most important subjects in Class 12. As the CBSE exam approaches, students get busy preparing for different subjects. But an essential part of the is the practical exams which consist of 30 marks. Students must know all the experiments along with theorems, laws, and numerical to understand all the concepts of 12th standard physics in a detailed way.

Two experiments (8 + 8 marks) are asked from each section in the practical exam. Radio 1 live lounge volume 1 download free. The experiment records and activities consist of 6 marks, the project has 3 marks and viva on the experiment consist of 5 marks. The Physics Practicals For Class 12 CBSE is given here so that students can understand the experiments in a better way. Students are suggested to study the theory and law behind the experiment properly before performing the experiment.
