My Independent Variable is the amount of water I use.

My Dependent Variable is the amount of voltage I measure.

My Control Variable is the amount of electricity put into the water.

My Hypothesis is that I think increasing the amount of water, without changing the amount of electricity put in, will create more voltage because there are more hydrogen and oxygen molecules available to create electricity.

My Problem is "will different amounts of water produce diffrent amounts of electricity?"

My Question is "will one cup of water generate more or less volts of electricity than two or four cups?"
