The present invention relates to a device for measuring resistance and internal resistance using resonant oscillation comprising: an output resonant oscillating unit having an output connectors connected to a target object to be mea-sured resistance or internal resistance to form a closed circuit and causing the resonant oscillation in the closed circuit; an inductive pulse generating unit for generating inductive pulses according to a pulse frequency, so that generating an output induced current in the closed circuit; and a measurement unit. While there is an output induced current appeared in the output resonant oscillating unit will generate a measurement inductive current in the measure-ment unit and measured and calculated to determine the resistance value of the target object to be measured resis-tance or internal resistance.

 

The output resonant oscillating unit including an output inductive copper bar and a mea-surement inductive copper bar, both play a role for gener-ating the inductance in the closed circuit which is composed by the output resonant oscillating unit and the target object to be measured resistance or internal resistance for coupling with the resonant capacitor assembly generating resonance oscillations while there is a suitable pulse frequency; play a role for generating the electromagnetic induction with the output resonant oscillating unit and the measurement unit; and play a role for generating at least a part of load bearing structure of the mounting structure.

 

In addition, the present invention may be capable to determine the natural oscilla-tion frequency of the closed circuit which is composed by the output resonant oscillating unit and the target object to be measured resistance or internal resistance.
