NIOS PHYSICS 312 PRACTICAL MANUAL HELP BOOK IN HINDI MEDIUM

Here We Provide NIOS Practical Lab Manual & Practical Examination Guidelines for 12th Class with important Experiments, Marking Scheme.

Guidelines for Nios (312) Physics Practical Examination Senior Secondary Level

Duration : 3 hours              There will be a practical examination of 20 marks apart from the theory examination.

The distribution of 20 marks is as follows:

(i) Viva – 3 Marks
(ii) Record Book – 3 Marks
(iii) Two Experiments (7 marks each) – 7+7 = 14 Marks (they should not be from the same group)

List of Practical works :

(i) Determine the internal diameter and depth of a cylinderical container using a vernier callipers and find its capacity.

(ii) Determine the least count of a screw gauge.

(iii) Set up a simple pendulum swinging freely about a sharp point of suspension and measure its time period accurately.

(iv) Set up a point in equilibrium under the action of three forces.

(v) Establish that a body gains or looses that because its temperature is blow or above that of the surrounding.

(vi) Understand the principle of heat exchange.
(vii) Observe how the volume of water in the burette varies with time as water flows out.
(viii) Set the resonance tube apparatus.
(ix) Select a suitable convex lens which forms a converging combination with the given concave lens.
(x) Draws emergent rays corresponding to rays incident on the face of a prism at different angles.
(xi) learn and understand that when a ray of light travels from a rarer medium to a denser medium, it bends towards the normal at the point of incidence.
(xii) Correctly place an eye lens and an objective lens on the optical bench so that these make an astronomical telescope.
(xiii) Make connections of an electrical circuit according to a circuit diagrams.
(Xiv) Find the least count of a screw gauge.
(xv) Explain the principle of operation of a potentiometer and the meaning of null point.
(xvi) Explain the principle behind the experimental determination of L and r.
(Xvii) Observe galvanometer deflection versus time for a given set of R and C values.
(Xviii) Understand how to forward bias a p-n junction and how to reverse bias it.
(Xix) Find the N and S-pole of a bar magnet.
(Xx) Know the type of meter simply by looking at the dial and distinguish between a galvanometer , a voltmeter and an ammeter.
