The electricity flows from the hot wire black through the 2 way switch shown in off position and then to the light and returns through the neutral wire white. You will see that there is a hot wire that is then spliced through a switch and that then goes to the hot terminal of the light. This method is commonly used nowadays as it is efficient than the two wire control system.
