How do we get lead?
Brass
Brass, which is made from copper and lead.
A alloy of copper, zinc, and tin is not a solution but an alloy of metals. An alloy is combination of metals which have been made into one while a solution is one or more substances being dissolved into another.
92.5% silver and 7.5% other metals usually copper, but sometimes zinc or platinum
The correct spelling is 'cuprous', and means copper-conatining. Some cuprous metals are, copper (obviously), brass, and bronze

When two different metals are pushed into a potato a voltage can be measured across the metals. The same is true for many fruits and vegetables. The reason is that chemicals, normally acids, in the fruits or vegetables react with the metals and generate a voltage. Good metals to try are copper and brass but others are worth using as well. The chemical compositions vary and so does the voltage. Potatoes are known to give a higher voltage than many others. For those who have the inclination, try various metals and fruits to find the highest voltage. It is this same principle on which batteries are based. Unfortunately, fruit is not quite as good as a purpose made battery so don't expect to be running any high power devices from a lemon when you try it.

Brass is an alloy of copper and zinc.
There is not much difference in either case. The voltage can be increased by putting vegetable that you have mentioned in series. By increasing the voltage, charge can be increased and it can be used to power small light bulbs.
If you are referring to a 'fruit cell' then, in common with all cells, the voltage is determined by the materials from which the electrodes are made -not by the fruit itself. The further apart the metals are on the 'electrochemical series' of elements, the higher the resulting voltage -so, for copper and zinc, the voltage will be about 1.1 V.
copper and aluminium are metals since their metals the effect is that their good conductors
We use copper because copper is one if the stronger metals that we have in the USA. Copper is also one of our most valued metals there are.
