Overpotential test set
The four possible polarities of overpotentials are listed below. • An electrolytic cell's anode is more positive, using more energy than thermodynamics require. • An electrolytic cell's cathode is more negative, using more energy than thermodynamics require. • A galvanic cell's anode is less negative, supplying less energy than thermodynamically possible. WebHipot Test is short name of high potential (high voltage) Test and it is also known as Dielectric Withstand Test. A hipot test checks for “good isolation.” H...
