Either raise the floor or un-solder the flange and lower it
Soldered joints will have a higher resistance if the joint is not a clean solder joint. Badly soldered joints are classed as a cold solder joint. <<>> ...for what? Application matters here.
It is very weird and I am gonna help. Zinc and copper create a higher voltage than copper and copper because zinc has a higher voltage than copper so copper plus zinc equals more than copper plus copper.
Copper
copper would have a higher U value
castings made from copper alloy are a higher grade of copper than the copper in wire. Also, the insulation on the copper wire needs to be removed,
Iron can be used to get copper from Copper Sulfate because it is more reactive than Copper (higher up in the reactivity series).
No, aluminum has a higher resistance than copper.
To give a higher surface area for the reaction
Nickel cannot replace copper in copper II sulfate because nickel is higher in the electromotive series than copper.
Zinc becomes plated with copper.
Copper
The iron is higher in they reactivity scale than copper , Therefore the copper will be replaced by iron to make iron sulfate and copper by itself.
