Q:
I have to do a science project for school in which I must make a lemon battery, but I need alot of voltage, so I thought of connecting many lemons together, how could I do this? Is it possible?

A:
Certainly. You can put lemon batteries in series to get a higher voltage just the same way that you put store-bought batteries together. You connect the positive electrode of one to the negative electrode of the next, making a chain.

Although you can get a large voltage this way, in my experience lemon batteries can't deliver much current.Use metal electrodes with large areas to try to get decent current-carrying ability.
