WebbE cell = oxidation potential + reduction potential. Since the tabulated standard electrode potentials are reduction potentials, the one which is most negative will need to be reversed in sign to get its oxidation potential. When that is done, it is clear that the theoretical standard cell potential for the zinc-copper cell is 1.10 volts. Webb22 feb. 2024 · Power is voltage multiplied by current: P = V x I To achieve the same amount of power, increase voltage will reduce current. For example, to produce 1000W, it takes nearly 60A on 4S (at 16.8V) while it’s only under 40A on 6S (at 25.2V). Lower amp draw translates into: Less stress placed on your battery WebbUnder theoretical cell voltage conditions, for both half-cell reactions (HOR and ORR) there is no net reaction.
