FIELD: physics.
SUBSTANCE: during discharge of chemical source of current (CSC) at condenser load a time of condenser discharge to a desired level is measured at three points. First point corresponds to the charge beginning, and the other two points are set at the ending time of condenser charge. Resistance is calculated by the formulae: r0=t1/n1C, Ohm; R=(t3-t2)/(n3-n2)C, Ohm; rn=(R-r0), Ohm, where r0 is internal resistance of CSC, rn is polarisation resistance of CSC, R= (r0 + rn) is cumulative internal resistance of CSC, t1 is time of condenser charge to the first voltage value, t2 is time of condenser charge to the second voltage value, t3 is time of condenser charge to the third voltage value, n1 n2, n3 are number of charge time constants corresponding to its charge to a given level.
EFFECT: wider functional capabilities; faster measurement and simpler process of measurement.
