How to generate

Initial setup

• Verify you have python 3 installed by running python3 --version
• Verify you have pip installed by running pip --version
• Install pygame by running pip install pygame

Plate capacitor

• Put your readings into plate_capacitor/readings.txt. Type of whitespace characters shouldn't make any difference, bacause readings form is defined separately
• (Optionally) Chose one of the ready graphical settings in plate_capacitor/config.py
• (Optionally) Feel free to add new or modify existings graphical settings in plate_capacitor/Graphical_settings.py
• Run python3 plate_capacitor/run.py

If readings were read succesfully, something like that should appear in the console:

Plate capacitor

• Put your readings into circular_capacitor/readings.txt. Format of this file is as follows:

  • Column 1: Distance from the middle of n-th point (cm)
  • Column 2: Electric potential of n-th point on line I |
  • Column 3: (...) on line II
  • Column 4: (...) on line II

• Set value-related settings in circular_capacitor/config.py in accordance with comments

• (Optionally) Modify display options in circular_capacitor/config.py

• Run python3 circular_capacitor/run.py

If readings were read succesfully, something like that should appear in the console:

Loaded radiuses:
[27.0, 32.0, 39.0, 46.0, 53.0, 60.0, 68.0, 74.0, 81.0, 87.0]

Loaded readings:
Column 1:  [6.7, 6.1, 4.6, 4.3, 3.6, 2.7, 2.3, 2.0, 1.4, 0.9]
Column 2:  [6.9, 5.9, 5.0, 3.8, 3.5, 2.9, 2.2, 1.8, 1.4, 1.0]
Column 3:  [7.2, 5.4, 5.2, 4.4, 3.2, 2.9, 2.3, 1.7, 1.3, 1.0]

Other capacitors (*)

*Other capacitors are not implemented, but can be generated, by setting structure parameter of class Data_reader. See how BASIC_STRUCTURE is defined. Baisically if you have readings:

                 2.28
           2.21  2.59
           2.14  2.66
2.04       2.14  2.46

then:

structure = [
  [False, False, False, True],
  [False, False, True,  True],
  [False, False, True,  True],
  [True,  False, True,  True],
]
