Centroidal-polygon: a new modified euler to improve speed of resistor-inductor (RL) circuit equation

Two circuits consist of first order equation. There are Resistor-Capacitor (RC) and Resistor-Inductor (RL). For this research, the researcher will be focused on the RL circuit equation. The Centroidal-Polygon (CP) scheme will be tested using SCILAB 6.0 software to ensure that the new scheme (CP scheme) can improve the speed. For the first order circuit equation, the complexity is focused on the time complexity, which is speed of the time taken to complete the simulation, which is the time complexity in the electrical part. To show the CP scheme is the best scheme, the CP scheme will be compared with the previous research, Polygon (P) by ZulZamri and Harmonic-Polygon (HP) by Nurhafizah. The result shows that the CP scheme is less computational and can be an alternative to solve the first order circuit equation and get the result quickly compared with the previous research.
