Law of conservation of energy states that energy can neither be lost nor created but can be transformed from one form to another. When powering a stereo speaker, electrical energy is transmitted through wires and is then converted to sound energy in the stereo speaker. Therefore, A. energy is neither lost or gained as electrical energy is transformed into the energy of sound.
