Analysis of RC circuits with the help of LabVIEW and data acquisition card for physics laboratory course

Abstract

In this study, it is aimed to create a circuit and software that can be used in teaching RC circuits at the university level for physics laboratory courses. In this context, the change of the voltage on the capacitor and the current of the circuit during the charge/discharge of an RC circuit connected to DC voltage was taken into the computer environment with a data acquisition card (NI USB 6021) and LabVIEW program. The experimental procedure to be applied in the use of the teaching material (circuit and software) developed within the scope of the study was explained in detail. Furthermore, in order to test the accuracy of the circuit and software, experiments were performed using different resistors and capacitors and presented in the scope of the study. As a result, the importance of the developed experimental setup in terms of teaching was emphasized.

Fizik laboratuvarı dersi için RC devrelerinin LabVIEW ve veri toplama kartı yardımı ile analizi

Abstract

Bu çalışmada, fizik laboratuvarı dersi için üniversite düzeyinde RC devrelerinin öğretiminde kullanılabilecek bir devre ve yazılım oluşturulması amaçlanmıştır. Bu kapsamda DC gerilime bağlı bir RC devresinin şarjı/deşarjı sırasında kondansatör üzerindeki gerilimin ve devre akımının değişimi bir veri toplama kartı (NI USB 6021) ve LabVIEW programı ile bilgisayar ortamına alınmıştır. Çalışma kapsamında geliştirilen öğretim materyalinin (devre ve yazılım) kullanımında uygulanacak deneysel prosedür detaylı olarak anlatılmıştır. Ayrıca devrenin ve yazılımın doğruluğunu test etmek amacıyla farklı dirençler ve kondansatörler kullanılarak deneyler yapılmış ve elde edilen sonuçlar çalışma kapsamında sunulmuştur. Sonuç olarak, geliştirilen deney düzeneğinin öğretim açısından önemi vurgulanmıştır.
