The existing indirect methods for electrical parameters’ measurement of two-terminal elements exhibit a substantial limitation. Such parameters as resistance, inductance and capacitance are determined by means of current, voltage or power measurement and calculation using relevant formulas. Accuracy of these procedures is lowered by internal impedance of the applied meters. In the paper, there are proposed a few modifications of the well-known indirect methods aimed at eliminating their errors.
