Physics MasterLab

Physics MasterLab is an interactive webbased simulation platform designed to demonstrate key concepts from physics through visual and experimental learning. Instead of static diagrams, this project allows users to explore real-time behavior of systems across thermodynamics, electrical circuits, and semiconductor physics.

Overview

This project brings together three core laboratory experiments:

• Carnot Cycle (Thermodynamics) Visualizes the PV diagram and explains heat engine efficiency.

• Wheatstone Bridge (Electric Circuits) Simulates resistance balancing and null detection.

• PN Junction Diode (Semiconductors) A fully interactive I–V characteristic simulator with forward and reverse bias behavior.
