1 teaspoon of salt produced -2.38 volts of electricity. 3 teaspoons of salt produced -7.06 volts of electricity. 5 teaspoons of salt produced -8.03 volts of electricity. The cup which produced the most electricity was the one with 5 tablespoons of salt. This is because the more salt there is, the bigger the charge (more electricity).
