From simple to complex form of circuits, actively support the establishment of new innovations in engineering technology. To build a good concept of circuit, it is necessary to have proper understanding on basic concept and circuit analysis. Starting from Ohm and Kirchhoff's laws, another circuit laws and formulas are derived from analysis and theorems, to give better calculation and solution in problems. This paper will do an analysis on relationship between resistances in delta circuit, and apply basic electric circuit theory to calculate the total resistance. This analysis is conducted by doing comparison and calculation to derive the expected formula.
