Introduction¶
Water¶
We use it for drink, wash, cooking!.
Wikipedia has some good text on water.
Why water?¶
Why Water is choosen as target. Reason: Availbility, No danger, and additional stuff. so, try different liquids. :) Also, it is not just water, it has impurities and Salt in it.
Resistance of Water¶
Water has resistance and we will explore how resistance varies with different amount of salt mixed in it.
AC/DC resistance¶
Lets see how water behave when a AC and DC signal is passed through it!
DC¶
After connecting, we start Box0 Studio and set as following:
| Name | Value |
|---|---|
| Waveform | "Constant" |
| Frequency | Not Applicable |
| Offset | "0V" |
| Amplitude | "3V" |
| Phase | "0◦" |
and run Oscilloscope (in stream mode, you can you static mode too.) configuration: enable "CH0" and "CH1".
AC¶
After connecting, we start Box0 Studio and set as following:
Run Function Generator with configuration:
| Name | Value |
|---|---|
| Waveform | ""Sine"" |
| Frequency | "10 Hz" |
| Offset | "0V" |
| Amplitude | "3V" |
| Phase | "0◦" |
and run Oscilloscope (in stream mode, you can you static mode too.) configuration: enable "CH0" and "CH1".
Conclusion¶
So, we can compare the peak voltage and see that in:
AC: CH1 is around 0.4V for (10Hz, 3V Sine wave)
DC: CH1 is less than 0.14V (3V, Constant)

TODO¶
- Offset correction needed. caliberation is required
- The experiment was performed on older version of software. Oscilloscope and function generator UI has changed considerably. Major Change: Function generator, "Constant" use Offset instead of Amplitude input.
