What is a common use for a transformer in power distribution?

• A. To rectify AC to DC
• B. To stabilize voltage levels
• C. To step up or step down voltage levels
• D. To filter electrical noise

Answer: (C)

Transformers are essential components in power distribution systems because they are specifically designed to modify voltage levels for efficient power transmission. The primary function of a transformer is to step up (increase) or step down (decrease) voltage levels. This is critical in power distribution because high voltage is typically used for long-distance transmission to minimize energy losses due to resistance in the wires. When power reaches its destination, transformers step down the voltage to safer, more usable levels for residential and commercial use. Understanding this role helps clarify why transformers are integral in managing voltage levels across the electrical grid, ensuring that the electrical supply is both efficient and safe for end-users.
