Objective: Determining impedance in a circuit with an inductive and a capacitive reactance
AC circuits with inductive and capacitive reactances show resonant behaviour. At the resonant frequency, the impedance of a series connection of an inductive and a capacitive reactance is zero, whereas the impedance of a parallel connection is infinite. This experiment examines this phenomenon with the help of an oscilloscope and a function generator which supplies voltages between 50 Hz and 20,000 Hz.
