8/29/17 Solderless Breadboards, Open-Circuit & Short-Circuit

Solderless Breadboards, Open-Circuits and Short-Circuits 

Date: 8/29/17 

Overview 

This lab will give an understanding of breadboards and measuring resistance using a Digital Multi Meter (DMM). 

Lab Procedure 

1) Use a DMM in two holes in the same row on the beard board and record resistance as in the figure. 

2) Check resistance of two separate rows using the DMM. Record results. 

3) Check two different rows of breadboard between Node A and Node C. Record results 

4) Use a jumper wire (simply a wire) to connect two different nodes, use DMM at each node. Record Results. 

Observation 

1) Lab procedure 1 is the result of a short circuit resulting in a low DMM reading of 0.4 Ω.

2) Lab procedure 2 is an open circuit resulting in a very high or infinite DMM reading of " 1 " meaning infinite value. When turning the "Ω." dial from 200Ω to 2000kΩ, reading continues to be "1", an open circuit. 

3) Lab procedure 3 resulted in the same results of lab procedure 2, resulting in a open circuit with a DMM reading of "1."

4) Lab procedure 4 resulted in the same results as lab procedure 1, resulting in a closed circuit with a reading of 0.5 Ω.
