Introduction to DC Circuits
The first four pictures involve breadboards connected in different holes to the Ohmmeter in order to determine the resistance between the holes.
In this first picture, the leads of the DMM are connected to the two holes on the same row. The DMM states that it has 0.15 ohms of resistance.
In the second picture, the leads of the DMM are connected to the two holes of the opposite sides of central channel. This causes the DMM to show a "1" indicating that there are infinite resistance between the holes.
The third picture shows the two arbritary holes not in the same row being connected. Here, the results shows the same as the second picture in that there are infinite resistance between connecting these two holes.
The fourth picture shows four holes, two of them connected to one row and the other two connected to the row different from the first two holes. This gave made the Ohmmeter give the results of the same resistance as the first picture of 0.15 ohms of resistance.
On the last picture, this is the calculations done in class to show the Power vs. Time graph using the information of the current and volts vs time graph.
Summary
We preformed measurements of the resistance showing whether it's infinite or not. The time it isn't infinite is when the resistors are connected to the same row of holes or when they are connected connected to one row and the other two connected to the row different from the first two holes. The time the yare infinite is when two arbritary holes are not being connected in the same row.
