Solderless Breadboards, Open-circuits and Short-circuits

Purpose of this lab is to understand the equipment and basic circuits

We used breadboards and multimeters.

1. So we used multimeter to measure the resistance between two holes in the same row, there was little to none resistance

2. The resistance between two rows of holes on opposite sides of the central channel is very high, can be considered infinite

3. When we checked the resistance between two arbitrary holes of the breadboard, our multimeter recorded a very high resistance again.

4. When we used a jumper wire to connect two different rows on the bread board, we saw that the resistance was very low.


1 and 4 was short circuit due to low resistance and current flowing between them

2 and 3 was open circuit due to the infinite high resistance, no current was flowing between them

the resistance in 1 was around 0.7 ohms, closed circuit
the resistance in 2 was unmeasurable, higher than 1 million, open circuit
the resistance in 3 was unmeasureable, higher than 1 million, open circuit
the resistance in 4 was around 1 ohms, closed circuit
