What includes light bulbs and other electrical devices?

The correct answer refers to common electrical measurements, which encompass various components and devices that utilize electricity, including light bulbs and other electrical devices. Common electrical measurements include voltage, current, power, and resistance, which are essential for understanding how these devices operate and interact within an electrical system.

Light bulbs, for example, require a specific voltage to function correctly, and their brightness is often related to the power consumed, measured in watts. Understanding these measurements is crucial for anyone involved in utility marketing, as it helps in promoting energy-efficient products and educating customers about their energy usage.

The other options, while related to electrical concepts, do not specifically focus on the components like light bulbs and devices. Power transformation deals with changing voltage levels in electrical power systems, voltage control involves maintaining voltage levels within a certain range, and electrical distribution refers to the process of delivering electricity from generation sites to consumers. These concepts offer valuable insights but do not directly address the inclusion of devices like light bulbs.
