Electrolysis of solutions - if the metal is positive it will discharge, other Hydrogen will, if non-metal is a halogen it will discharge, otherwise OH

I GOT THE POWER

 

How did those get on there in the first place?

galvanising = cover metal with more reactive metal which forms a protective oxide coat, protects inner metal from rust

 

or use cathodic protection by connecting to a more reactive metal (magnesium) the sacrificial anode

in copper purification other more reactive metals may be discharged into solution, but they will not reduc onto pure copper anode as long as the less reactive Cu metals ions are still in solution (Cu ions wants them electrons more than they do)

the capacity depends on the quantity of electrolyte (no use you have material that could still react if no electrolyte to carry charges)

Current depends on the SA of the electrodes (.: electrodes are porous) as th reaction making the current can be affected by the general reaction rate stuff

current also depends on internal resistance which is greater if the electrodes are further away and is greater if the electrolyte concentration is lower

the leclanche cell's emf is 1.5V initially, though this drops as current is drawn off and deteriorates in cold weather

the alkaline dry cell is much like the leclanche but the NH4Cl is swapped with KOH, the battery performs better under current drain and low temps
