Hanna %J International Journal of Electronics and Computer Science Engineering %D 2013 %I Buldanshahr : IJECSE %X The conditions of stability have been studied by criteria depended on polynomial of degree four got from a system of Differential Equations of Kirchhoff's law, this exactly which the paper discussed and the Kirchhoff's system has form: Where { }q is the charge on the capacitor, [ ] L is the inductance and cS1= , where c is the capacitor.Which represent the voltage drop across the capacitor and inductance. %K Differential Equations %K Stability %K Kirchhoff's System %K Criteria of Stability %K Characteristic Polynomial. %U http://www.ijecse.org/wp-content/uploads/2012/12/Volume-2Number-1PP-168-174.pdf
