Suppose you have a circuit in which you have connected 3 batteries, each of which that has voltage of 2.2V, in series with each other such that the positive terminal of one battery is connected to the negative terminal of the next (and so on), what is the resulting voltage? Note: It is understood that the unit of your answer is in Joules (J), however do not explicitly include units in your answer. Enter only a number. If you do enter a unit, your answer will be counted wrong.
