ENGINEERING PHYSICS - II PRACTICAL

LIST OF EXPERIMENTS WITH OBJECTIVES:

1. REFRACTIVE INDEX To determine the refractive index of a transparent liquid (water) using travelling microscope.

2. SPECTROMETER. To measure the angle of the prism and the angle of minimum deviation using spectrometer and to calculate the refractive index of glass.

3. SOLAR CELL. To draw the V – I characteristics of the solar cell.

4. LAWS OF RESISTANCES. To verify the laws of resistances by connecting the two given standard resistances (i) in series and (ii) in parallel, using Ohm’s law.

5. METRE BRIDGE. To determine the unknown resistance of the given wire.

6. POTENTIOMETER. To compare the electro motive forces (e.m.fs) of the given two cells.

7. JOULE’S CALORIMETER. To determine the specific heat capacity of water.

8. COPPER VOLTAMETER. To determine the electro chemical equivalent (e.c.e.) of copper.

9. P-N JUNCTION DIODE. To draw the voltage – current characteristics in forward bias and to find the ‘dynamic forward resistance’ & ‘knee voltage’ from the graph.

10. LOGIC GATES. To find the output conditions for different combinations of the input for NOT gate and 2 inputs AND, OR, NAND & NOR logic gates, using IC chips. ( IC 7404 –NOT Gate, IC 7408 – AND Gate, IC 7432 – OR gate, IC 7400 – NAND Gate, IC 7402 – NOR Gate)
