Description

In the experiment P3.6.1.4, the function generator generates periodic square-wave signals which simulate switching a DC voltage on and off. The current and voltage are recorded by Mobile-CASSY 2. The aim of the experiment is to determine the time constant

for various capacitances C from the exponential curve of the respective charging or discharge current IC.
