Physics Practical (Class 12)

The document uploaded consists of the complete & checked Physics practical file that is required at the time of submission in Final Board Practical of Class 12. The file is complete & consists of the full data that is required in different experiments along with the required graphs. The file consists of the following practicals :-

1. To determine the resistance per unit length of a given wire by plotting a graph of Potential difference vs Current.
2. To determine resistance of a given wire using metre bridge& hence determine the specific resistance of the material.
3. To verify law of combination of resistance using metre bridge.
4. To compare EMF of two given Primary cells using a Potentiometer.
5. To determine the internal resistance of given primary cell using a Potentiometer.
6. 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.
7. To find the focal length of a convex lens by plotting graph between u &v or 1/u & 1/v.
8. To find the focal length of a Convex Mirror using Convex lens.
9. To find the focal length of a Concave lens using Convex lens.
10. 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.
11. To draw the I-V Characteristic curve of a p-n junction diode in forward bias & reverse bias & to determine its static & dynamic resistance.
12. To draw the I-V Characteristic curve of the given Zener diode in reverse bias.
13. To study the characteristic of a Common Emitter npn or pnp transistor & to find out values of current & voltage gains.
