Final answer:
A computer or device typically receives power from a power supply or battery, which transforms external voltage into the correct form for the device to use. Batteries store power that is often drawn from an electrical grid, which may include various sources like generators or wind farms. Solar panels can also provide power, particularly in photovoltaic cells where they transform solar energy into electricity.
Step-by-step explanation:
A computer or device receives and distributes power through option c. Power is received from the power supply or battery and is then distributed to the various components of the device. The power supply converts voltage from power lines for use in homes into the correct voltage and current needed by the computer. When not plugged into a power outlet, many devices operate on power stored in their batteries. These batteries may have received their charge from a direct connection to the power grid, which could come from a variety of sources, including current from power lines or current from an electrical generator. In the case of solar-powered devices, power is obtained from solar panels. However, the power for most computers and devices is not typically derived from solar panels alone but rather from the electrical grid. Moreover, various types of energy, such as heat, work, and internal energy, can be used to do work. For instance, in photovoltaic cells, solar energy is transformed into electric energy.
