polarization voltage

...The phenomenon in which the voltage U between the terminals of a battery deviates from _its value U0 when no current is flowing when a current is flowing through the battery system is generally called electrolytic polarization or electrochemical polarization. The difference _between U and U0 is called the polarization voltage, and its value changes depending on the magnitude and direction of the current. The polarization voltage of a battery is equal to the sum of the polarization voltage at each electrode system that makes up the battery and the ohmic drop due to the electrical resistance inside the battery (if the current is I and the internal resistance is R , the ohmic drop is given by IR ). ...

…電池系に電流が流れているときに，電池の端子間の電圧Uが，電流が流れていない状態での値U₀からずれる現象を，一般に電解分極または電気化学的分極electrochemical polarizationという。また，UとU₀との差を分極電圧polarization voltageといい，その値は電流の大きさや向きによって変化する。電池の分極電圧は，電池を構成している各電極系における分極電圧と，電池内部の電気抵抗によるオーム降下(電流がI，内部抵抗がRならばオーム降下はIRで与えられる)との和に等しい。…
