Question

In an galvanic cell one electrode has a excess of electrons and the other electrode has a deficiency of electrons. The electrode potential of the separate electrodes is measured using standard hydrogen electrode cell. But when we keep both the electrodes +and- together why not the access of electrons in one electrode decrease the potential of the other, by electrostatic potential learned in physics ie
V=kq/r2. please exp

Answer 1

because it gets balanced by electrons
