Title: Investigating and Verifying Ohm's Law

Introduction:

In this physics project, you will investigate and verify Ohm's Law, which states that the current flowing through a conductor is directly proportional to the voltage applied across it, while the resistance remains constant. Through research, virtual experiments, data analysis, and creating visual presentations, you will gain a deeper understanding of Ohm's Law and its practical applications.

Materials Needed:

Computer with internet access

Access to virtual circuit simulation tools

Graphing software (e.g., Microsoft Excel or Google Sheets)

Pen/pencil, paper, and ruler

Access to a printer for creating graphs and data sheets

Tri-fold display board for presenting your findings
