Analysis of magic table in completin of closed flow circuits

Abstract

Problem of two-loop electric circuits is classified in the material that has a high degree of difficulty for students. Its completion requires several processes and a thorough analysis, translation of problem languages in mathematical language, applying concepts, and making algorithms. Electrical circuit material is often put into several tests which is implemented on university selection exams or national exam. In solving problems, students need a relatively long time. More effective and efficient methods are needed to solve the problem of two-loop electric circuits. The purpose of this research is to describe the Magic Table as a new solution in solving the electric current of a two-loop circuit more easily. The method used is the Ohm law concept and principle of simplifying Thevenin and Northon circuits, so that a replacement voltage is obtained to find the current strength in the circuit. This research analyzes several types of two-loop circuits with varying voltage and resistor sources. The results showed the calculation analysis using the magic table is easier and simpler than the elimination and substitution methods. With the application of simple concepts and algorithm, the Magic Table can be applied as a new solution to solving the problem of two-loop electric circuits.
