===== Preparation for the oral short test =====

For this experiment you should
  - be able to apply and explain the following concepts:
    - current- and voltage-correct measurement
    - series and parallel connection of resistors
    - mesh and node equations (Kirchhoff's laws)
    - passive sign convention and active sign convention
    - ideal and real sources

You should be able to answer the following questions:
  - Which operating mode does the source use? Which quantity is kept constant by the source?
  - Power supplies operate in quadrants. In which quadrant is the power supply operated? What can the source then correspondingly not do?
  - What must be considered for the (loaded and unloaded) voltage divider?
  - How do you measure a voltage with a current meter? How a current with a voltage meter?
  - How does an ohmmeter measure resistance?
  - Where are the limits of linearity in real resistors?
  - What examples are there of linear and non-linear resistors?
  - What else can the resistance depend on?
