## CBSE Syllabus for Class 12 Physics Practical

Assessment Plan for Class 12th Physics Practical: The assessment includes these parts—Two experiments (one from each section), keeping a record of practical work [experiments and activities], one activity from either section, projects exploring investigations, and discussions on experiments and activities. Marks are assigned to each part individually, totaling to 30 marks for all sections together. The mark distribution for each section is shown in the table below:

List of Experiments for Class 12 Physics Practical: Section A

• Measuring Wires’ Resistivity: We’ll create a graph showing the relationship between how much power flows through wires and the voltage. This helps us understand their resistance.
• Finding Resistance: Using a meter bridge, we can figure out how much resistance a specific wire or a standard resistor has.
• Testing Resistance Arrangements: Using the meter bridge, we’ll check if resistors are connected in a row (series) or side by side (parallel) to see if they follow certain rules.
• Galvanometer Investigation: We’ll determine a galvanometer’s resistance using the half-deflection method and figure out its quality.
• Transforming Galvanometer: We can change a galvanometer into a voltmeter to measure different voltages and ensure it works accurately.
• Transforming Galvanometer into an Ammeter: Alternatively, we can convert the galvanometer into an ammeter to measure various currents accurately.
• Checking Mains Frequency: We’ll use a sonometer to find out the frequency of the electricity supplied to our homes.

List of Experiments for Class 12 Physics Practical: Section B

• Testing different values of u to find v for a curved mirror and determine its focal length.
• Using a convex lens to calculate the focal length of a convex mirror.
• Plotting graphs between u and v or 1/u and 1/v to find the focal length of a convex lens.
• Employing a convex lens to measure the focal length of a convex mirror.

• Determining the refractive index of a glass slab using a traveling microscope.
• Using a convex lens and a plane mirror to calculate the refractive index of a liquid.
• Utilizing a concave mirror and a plane mirror to find the refractive index of a liquid.

CBSE Syllabus for Class 12 Physics Practical: Activities Assigned

• Test the resistance and impedance of an inductor, whether it has an iron core or not.
• Use a multimeter to measure resistance, voltage (AC/DC), current (AC), and ensure continuity in a circuit.
• Create a basic household circuit using three bulbs, three on/off switches, a fuse, and a power source.
• Assemble the parts of a given electrical circuit.
• Explore how potential drop changes with wire length when a constant current flows.
• Draw an open circuit with a battery, resistor/rheostat, key, ammeter, and voltmeter. Identify incorrectly connected components, correct the circuit, and update the circuit diagram accordingly.
