Abstract

Research has been conducted on the comparison of the I-V characteristic curve between mathematical study and experiment of the generation of negative DC corona discharge in the Gradient Line-to-Plane (GL-P) electrode configuration. The reason for this research is to calculate the suitability of the corona discharge electrical current between the mathematical and experimental study. The active electrode used has length 2 cm and height 4 cm. This research is conducted with variations in the sharpness angle of the active electrode (θ) 300, 450, and 600 and variations in the distance between the electrodes () 2 cm, 3 cm, and 4 cm. The mathematical formulation of the value of the corona discharge electrical current in the configuration of the GL-P electrode is obtained by using the geometric concept approach, which is the formulation of the capacitance value of the ordinary electrical circuit, with the addition of the multiplication factor value k in the sharp area of the active electrode, because in that area the greatest plasma flow distance is obtained. The value of the multiplication factor  is obtained by fitting the curve between mathematical study and experiments. The I-V curve between the mathematical study and the corona discharge generation experiment has a high degree of similarity with the smallest percentage contacting point of 37.50%.The value of the multiplication factor  is influenced by the sharpness angle of the active electrode shape and the distance between the electrodes.

Abstract

This research aims to calculate thoroughness among data points and analytical simulation curves in discussing corona discharges' (I-V) characteristics. The electrode construction used is the twin towers with dividing angles to the plane (TTDA-P) model in air, with negative DC polarity. An asymmetrical electrical CCP model in the electrode design uses research variations, including active electrode center clamp angles of q = 300, 450, and 600 and active and passive electrode distances (d) of 0.002 m, 0.005 m, and 0.008 m. The simulation curve comes from the analytical formulation of the reduced capacitance type (inserting a multiplying factor k to the sharp corners of the active electrode), with the simulation program being a Python GUI program. The experimental results produced an appropriate error value (t-test value £0.05) and a high percentage of tangent points value. The best curve was achieved at q = 450 and d = 0.008 m, with a t-test value of 0.0313 and the highest percentage of significant tangent points of 92.31%. For all variations q, there is a tendency that the smaller the value of d (the gap length among two electrodes), the greater the deviation distance between the simulation curve and the data points.

Abstract

Hooke's Law is one of the topics in physics that can be simplified for better understanding through practical methods. This research aims to design a Real-Time remote Hooke's Law experiment in laboratory with Blynk as IoT Mobile Application, allowing students to experiment more flexibly in terms of time and location. The research methodology is based on Research and Development (R&D), including hardware design, software design, testing and data collection, data analysis, and report writing. This study resulted in the development of a laboratory Hooke's Law experiment and a Blynk application as its controller. The apparatus was tested by conducting experiments with three different loads: 30 grams, 40 grams, and 50 grams. The experiments aimed to obtain the spring constant, k, which were then processed using Hooke's Law formula based determine spring elongation data, ∆x. The 30 gram load yielded an average ∆x of 0.059 meters with an accuracy of 99.98% and an average k value of 4.90 N/m with an accuracy of 98.75%. The 40 gram load yielded an average ∆x of 0.059 meters with an accuracy of 99.93% and an average k value of 5.32 N/m with an accuracy of 95.40%. The 50 gram load yielded an average ∆x of 0.089 meters with an accuracy of 99.94% and an average k value of 5.53 N/m with an accuracy of 96.39%. The overall accuracy of the apparatus was 99.95% for ∆x and 96.18% for the spring constant. The system can choose the mass, m with control the stepper motor via mobile application and the result of research can be monitored in smartphone display such as such as spring elongation, ∆x, and spring constant, k as well as streaming video for monitoring purposes. [1]      Arsada, Bakhtiyar, and B.
