Hii aspirant..

The experimental topics in JEE mains syllabus are -

• Familiarity with the basic approach and observations of the experiments and activities:
• Vernier callipers - its use to measure internal and external diameter and depth of a vessel.
• Screw gauge-its use to determine thickness/diameter of thin sheet/wire.
• Simple Pendulum-dissipation of energy by plotting a graph between square of amplitude and time.
• Metre Scale - mass of a given object by principle of moments.
• Young’s modulus of elasticity of the material of a metallic wire.
• Surface tension of water by capillary rise and effect of detergents.
• Coefficient of Viscosity of a given viscous liquid by measuring terminal velocity of a given spherical body.
• Plotting a cooling curve for the relationship between the temperature of a hot body and time.
• Speed of sound in air at room temperature using a resonance tube.
• Specific heat capacity of a given (i) solid and (ii) liquid by method of mixtures.
• Resistivity of the material of a given wire using metre bridge.
• Resistance of a given wire using Ohm’s law.
• Potentiometer
• Comparison of emf of two primary cells.
• Determination of internal resistance of a cell.
• Resistance and figure of merit of a galvanometer by half deflection method.
• Focal length of: (i) Convex mirror (ii) Concave mirror, and (iii) Convex lens using parallax method.
• Plot of angle of deviation vs angle of incidence for a triangular prism.
• Refractive index of a glass slab using a traveling microscope.
• Characteristic curves of a p-n junction diode in forward and reverse bias.
• Characteristic curves of a Zener diode and finding reverse breakdown voltage.
• Characteristic curves of a transistor and finding current gain and voltage gain.
• Identification of Diode, LED, Transistor, IC, Resistor, Capacitor from mixed collection of such items.
• Using multimeter to:

(i) Identify base of a transistor

(ii) Distinguish between NPN and PNP type transistor

(iii) See the unidirectional flow of current in case of a diode and an LED

(iv) Check the correctness or otherwise of a given electronic component (diode, transistor or IC).
