Procedure

  1. Set up the circuit as shown in the diagram below using the connecting wires and components.mermaidCopy codegraph TD A(Battery) --> B(Ammeter) B --> C(Resistance Wire) C --> D(Voltmeter) D --> E(Battery)
  2. Gradually increase the current by adjusting the rheostat.
  3. Record the corresponding values of current (I) and voltage (V).
  4. Plot a graph of V versus I.
  5. Calculate the resistance using Ohm’s law: R = V/I.

2. Resonance Tube Experiment

Objective

To determine the speed of sound in air using a resonance tube.

Apparatus

  • Resonance tube
  • Tuning fork
  • Water
  • Vernier calipers
  • Thermometer

Procedure

  1. Fill the resonance tube with water.
  2. Strike the tuning fork and hold it near the open end of the tube.
  3. Gradually lower the tube into the water while listening for a loud resonance sound.
  4. Note the level of water at this point.
  5. Measure the temperature of the water using a thermometer.
  6. Calculate the speed of sound using the formula: Speed of Sound (v) = 2 * Length of Air Column (L) * Frequency of Tuning Fork (f).

Conclusion

Mastering Physics Practical for Class 11 requires dedication, precision, and a deep understanding of the concepts involved.
