Exam Pattern:
The practical exam is conducted for a duration of three hours and is divided into three sections:
- Section A: Experiments (30 Marks)
- Section B: Activities (05 Marks)
- Viva-voce (05 Marks)
Section A: Experiments (30 Marks):
This section is the heart of the practical exam, where you perform two experiments – one from each list below. Each experiment carries 15 marks (8 marks for observations and calculations, 7 marks for viva-voce based on the experiment).
List of Experiments (Section A):
| List 1 | List 2 |
|---|---|
| 1. Determination of resistance of a given wire using meter bridge. | 1. Determination of G using a stop watch and a screw gauge. |
| 2. Study the variation of potential difference with current across a fixed resistor using a potentiometer. | 2. Verification of Ohm’s Law. |
| 3. Determination of the refractive index of a liquid by the method of refraction through a prism. | 3. Determination of the specific heat capacity of a solid by the method of mixture. |
| 4. Trace the characteristic curve of a junction diode using a voltmeter and an ammeter. | 4. Verification of the laws of combinations of resistances in series and parallel. |
| 5. Finding the focal length of a lens by displacement method. | 5. Determination of the emf of a source and its internal resistance using a potentiometer. |
