Final answer:
Smartphones require various transfers and transformations of energy to operate, with electricity being the original source of energy.
Step-by-step explanation:
One technology that is commonly used is a smartphone. Smartphones require various transfers and transformations of energy to operate. The original source of energy for a smartphone is usually electricity.
When a smartphone is being charged, electrical energy is transferred from a power source, such as a wall socket, to the phone's battery. The battery then converts this electrical energy into chemical energy to store it. When the phone is turned on and in use, the battery releases the stored energy as electrical energy. This electrical energy powers the phone's components, such as the processor, screen, and speakers, which are designed to efficiently convert electrical energy into other forms of energy, such as light, sound, and kinetic energy.
Overall, the transfers and transformations of energy necessary to operate a smartphone involve converting electrical energy into various other forms of energy, allowing the phone to perform its functions.
