1 - Short and Open Circuit, Breadboards

INTRO: Today we used breadboards, which are boards where  certain rows or columns are connected, to demonstrate two different types of circuits.





Above is a picture of a breadboard. Certain rows and columns are connected, while others aren't, which makes it ideal when trying different circuit diagrams.


LAB: Solderless Breadboards, Open-circuits, and Short Circuits.

Here we used a multimeter, jumper wires, and a breadboard to measure resistance. It was a short so we measured 4.6 mOhms. For practical purposes, this can be considered practically 0. This makes sense as a short circuit has a resistence approaching 0.



For the next situation, the recording was above what we could measure. This happens because the points that the end of the multimeter were connected to were not connected at all. This causes a resistance approaching infinity. This case can be compared to holding the two ends of the multimeter up, separated above air.

Above are the results of the 4 situations attempted. A & D are open circuits, while B & C are short circuits

To summarize, the progression of circuits by increasing resistance you have short, closed, and open.
