| Abstract: | A method of determining the critical resistance is introduced from the relevant equation and the initial condition of the RLC series circuit. In the deficient damping resistance, the damping resistance formula, which is related with the vibration amplitude and damping ratio is derived, and the least square method is used to fit the experiment data. |

| Keywords: | critical damping resistance RLC series circuit transient state process degree of damping least square method |
