【Abstract】 By using Matlab software, a thorough analysis has been done on response to zero input for the second order series circuit of RLC discharge. The functional relations between the peak value of impulse discharge current expressed as i m and the corresponding time t m and the other parameters, such as R,L,C respectively, has also been presented. Based on the calculation and plotting, it has been proved that i=f(t), u C=f(t). u L=f(t),i m=f(R,L,C) and t m=f(R,L,C) could be described and calculated by using an uniform formula when R>2L/C or R<2L/Crespectively. Finally, a sort of method to seek for i m by using the theory of energy conservation was introduced and validated.更多还原
