電圧であり、式（１）から、 Ｖｎ≒Ｖｃ ・・・（２） となる。自然放電を無視すれば、Ｖｎ＝Ｖｃとなる。Here, an equivalent circuit of the capacitor 4 is shown in FIG.
As shown in the figure, the resistance is given by a series circuit of a DC resistance r and a capacitance C. Therefore, when a charging current ic consisting of a constant current is passed through the capacitor 4, a voltage drop Vr occurs in the DC resistance r and a voltage drop Vc occurs in the capacitor C as shown in FIG. When charged to Vm, the voltage Vm is as follows: Vm = Vr + Vc = r · ic + Vc (1) Then, the capacitor 4 is kept in the open state for a predetermined time T.
After the standing, the voltage Vn between the terminals of the capacitor 4 loses the voltage drop (r · ic) of the DC resistance r, and thus the voltage Vn between the terminals is a voltage held by the capacitance C of the capacitor 4. From equation (1), Vn ≒ Vc (2) If the natural discharge is ignored, Vn = Vc.

（＝ｒ・ｉｃ）である。Therefore, in the calculation step, the following calculation is performed by the calculation device 20. That is, the terminal voltage Vn is subtracted from the terminal voltage Vm, and as a result, a voltage drop ΔV is calculated. That is, the voltage drop ΔV is ΔV = Vm−Vn = Vr (3), and the voltage drop ΔV is the voltage drop Vr of the DC resistance r.

すことで、コンデンサ４の直流抵抗ｒが算出される。Therefore, from the equations (1), (2) and (3), Vr = r · ic = Vm−Vn = ΔV (4), and the DC resistance r of the capacitor 4 is r = (Vm− Vn) / ic = ΔV / ic (5) Therefore, the DC resistance r of the capacitor 4 is calculated by dividing the voltage drop ΔV by the charging current ic.
