Which type of transformer is used to step down voltage?

A step-down transformer is specifically designed to reduce voltage from a higher level to a lower level. This is achieved through the winding ratio of the primary and secondary coils. In a step-down transformer, the number of turns of wire in the secondary coil is fewer than in the primary coil, which causes the voltage to decrease while increasing the current.

This type of transformer is commonly used in various applications where a lower voltage is required for equipment operation, such as in power distribution systems where high voltages from transmission lines need to be converted to safer levels for residential or commercial use. The step-down mechanism is crucial for ensuring safety and compatibility with electrical devices that cannot operate at higher voltages. This is why the step-down transformer is the appropriate choice for stepping down voltage.
