GENERAL INSTRUCTIONS 1. All answers must be written in the answer booklet provided separately. 2. If square paper is used, it must be attached to the answer booklet. 3. Marks are given for a clear record of observations actually made, for their suitability and accuracy and for use made them. 4. Copy aim from question paper. Write Statement of theory, observations, observation table, calculation and result in your answer booklet. 5. Candidates are advised to record their observations as soon as they have been made. 6. All working including rough work should be done on the same sheet as and adjacent to the rest of the answer. 7. Mathematical tables, graph papers and square papers are provided. The intended marks for questions or parts of questions are given in brackets [ ]. 8. Note: Procedure of the experiment, ray diagrams and precautions are not to be written in your answer booklet. SEACTION A (EXPERIMENTS) (07) 1. To determine resistivity of two / three wires by plotting a graph for potential difference versus current. 2. To find resistance of a given wire / standard resistor using metre bridge. 3. To verify the laws of combination (series OR parallel) of resistances using a metre bridge. 4. To determine resistance of a galvanometer by half-deflection method and to find its figure of merit. SEACTION B (EXPERIMENTS) (07) 5. To find the value of v for different values of u in case of a concave mirror and to find the focal length. 6. To find the focal length of convex lens by plotting graphs between (a) u and v (b) between 1/u and 1/v. 7. To find the refractive index of a liquid by using concave mirror and plane mirror. 8. To find the refractive index of a liquid by using a convex lens and plane mirror. 9. To draw the I-V characteristic curve for a p-n junction diode in forward and reverse bias. ACTIVITIES (03) 1. To measure the resistance and impedance of an inductor with or without iron core. 2. To measure resistance, voltage (AC/DC), current (AC) and check continuity of a given circuit using multimeter. 3. To assemble the components of a given electrical circuit. 4. To observe refraction and lateral deviation of a beam of light incident obliquely on a glass slab. 5. To study the nature and size of the image formed by a (i) convex lens, or (ii) concave mirror, on a screen by using a candle an screen (for different distances of the candle from the lens/mirror). 6. To identify a diode, an LED, a resistor and a capacitor from a mixed collection of such items.  Practical record (experiments and activities) (05)  Investigatory project (03)  Viva voice (05) Page 1 of 1
