…showed last 75 words of 499 total…higher current than fruit. PROCEDURE 1. I inserted the copper and steel plate into each fruit then I connected heads to each and measured the voltage of each fruit. 2. I recorded the data. 3. I connected alligator clips to the light bulb, tested all fruits. 4. I recorded the results of how long the bulb stays lit. 5. If the bulb does not light up we will connect more fruits together to produce more electricity. 6. Record all the data.
