All things are in place to have functional cell. Which of the following statements is FALSE? Nothing will happen until you add an external power source. O Without a power source, electrons will travel from the aluminum beaker to the copper beaker You can run this as a voltaic cell and get out a maximum of 2.00 V You can run this as an electrolytic cell only if you input a minimum of 2.00 V
