Two metals are used to make batteries. Would a battery in which both metals components are copper, make a good battery? Explain your reasoning.

Question

No, they have to be dis-similar metals. The farther apart from each other on the galvanic series the better.

@Lemons okay thanks(: is that a good explanation though?

imqwerty · Answer

the current in a flows because of the potential difference at the 2 poles.
if both metals are copper than the potential difference will be 0 so current will not flow.
So therefore both the metals shuld be different.

@imqwerty wow im surprised.. thanks

@imqwerty wait did you mean the current doesn't flow? in the first line

imqwerty · Answer

no sry i mean like both poles made of same metal will not create potential difference and therefore they won't generate power.

:)
a battery's wrk is to generate power and cuz of same potential difference it won't be able to generate power
