Physics Lab File
Welcome to the Physics Practical File, a comprehensive resource designed to help students perform and understand key experiments essential for mastering fundamental physics concepts. This file includes detailed procedures, observations, calculations, and conclusions for various practicals that align with the NEB curriculum.
List of Experiments:
- Determination of Viscosity by Stokes’ Theorem – Measuring the viscosity of a liquid by studying the motion of a falling sphere.
- Simple Pendulum – Determining acceleration due to gravity by analysing the time period of a pendulum.
- Pole Strength and Magnetic Moment of a Bar Magnet – Investigating the magnetic properties of a bar magnet.
- P.O. Box (Post Office Box Method) – Measuring unknown resistance using the Wheatstone bridge principle.
- Resonance Tube Experiment – Determining the velocity of sound in air by observing resonance in a closed tube.
- Meter Bridge – Using the principle of the Wheatstone bridge to measure unknown resistance.
- Sonometer – Calculating the frequency of AC mains by using a sonometer..
- Potentiometer – Comparing EMFs of two cells and determining the internal resistance of a cell.
- P-N Junction Diode Characteristics – Analyzing the current-voltage characteristics of a diode in forward and reverse bias.
Each experiment is structured to enhance conceptual clarity and develop essential laboratory skills. This practical file serves as a valuable guide for students to record their findings systematically while reinforcing theoretical knowledge through hands-on learning.
