Volts and Current
Having a simple circuit we establish the relationship between Volts, Current and Power
Running a test with a Ammeter, we understand that the Current is constant throughout the system. (before and after the lap)
Reiterating the statement above, the analogy can be made with the water generator and stream. The water is never lost, it just looses energy.
Resistance
We used a voltage generator and ran it at different volts. In the circuit we had a coil which had a unknown amount of wire wrapped around it (using it as the resistance). and we were able to find a relationship between Voltage, Current, and Resistance
As seen above the Voltage and Current are directly proportional. The slope of the V-vs-I graph indicates the amount of resistance. The higher the slope of the linear graph, the greater the resistance.
The data collected with different coils, different lengths, and different material. This gives us a good way to determine the relationship of Resistance with either one of those other factors.
Relationships between Resistance and different attributes of a wire.
