A voltaic cell, also known as a galvanic cell, generates electrical current by harnessing the energy released by a spontaneous chemical reaction. The flow of electrons from one electrode to the other through an external circuit produces electrical energy that can be used to power devices. Therefore, choice A is the correct answer.
