The term for the device that converts higher voltage to lower voltage is a step down transformer. This type of transformer is specifically designed to reduce voltage levels while maintaining the same frequency. When electrical energy is transmitted over long distances, high voltages are used to minimize the energy loss due to resistance in the wires. However, for safe and practical use in homes and businesses, these higher voltages must be lowered.

The step down transformer operates by having more turns of wire in the primary coil compared to the secondary coil. As a result, when an alternating current passes through the primary coil, it induces a lower voltage in the secondary coil, effectively stepping down the voltage to a usable level.

Understanding the functionality of a step down transformer is crucial in various applications, particularly in electrical distribution systems where safety and efficiency are paramount.
