Introduction

Understanding basic elements and operating principles of simple circuits is a crucial foundation for

building and understanding (more complicated) digital circuits. This simulation is meant to introduce

basic circuit principles to students with no or little background.

Purpose

The purpose of this lab is to:

Gain experience with online simulations and experimentation, and

Gain an understanding of Ohms Law by explaining how resistance, current and voltage are

related.

Simulation and Questions

We will use a simulation entitled, Ohms Law, located at

https://phet.colorado.edu/en/simulation/ohms-law

1) What are three different combinations of I and R that achieve a voltage of 6.0 Volts?

2) Describe the relationship between I and R. Why is this?

3) What would happen if you could decrease the resistance to 0? Explain.
