Lab 1: Solderless Breadboards, Open-circuits and Short-circuits

Solderless Breadboards, Open-circuits and Short-circuits

Overview: 

The purpose of this lab assignment is to provide users with an introduction to some of the equipment which will be used in subsequent lab assignments. The following topics are discussed: 

• breadboards

• use of digital multimeters (DMMs) to measure resistance.

The purpose of this lab assignment is to provide users with an introduction to some of the equipment which will be used in subsequent lab assignments. We used breadboards and digital multimeters(DMM) to complete the lab activity. We examine the connections between different holes in a breadboard using a DMM as an ohmmeter. We see which connections correspond to open circuits and short circuits. We also use jumper wires to change the connectivity between holes on the breadboard.

( Short circuit with connected through metal of the bread board)

(Infinite resistance when two piece not connected)

(It shows the resistance of 0.7omh when connected with one wire)

1. Provide the resistance you measured between two holes in same row. State whether these operate as open or closed circuit.

R = 0.4 Ohm

(Short)

2. Provide the resistance you measured between two holes opposite sides of channel. Characterize as open or closed circuit.

R = 1 Mega Ohm

(Open)

3. Provide the resistance you measured between two arbitrary holes in the breadboard. Characterize as open or closed circuit.

R = 1 Mega Ohm

(Open)

4. Provide the resistance you measured between holes connected by a jumper wire. Characterize as open or closed circuit.

R = 0.7 Ohm

(Short)

Conclusion:    In this lab, we used different combination of wires to make different circuit to see which one is works. Above picture shows that enable for it to function, one have to be connected. Once the they are connected, current show shown on DMM machine.
