Which transformer converts high voltage low current into low voltage high current?

The step down transformer is designed specifically to convert high voltage, low current electrical energy into low voltage, high current electrical energy. This transformation occurs through the principle of electromagnetic induction, where the primary winding receives a high voltage input, and the magnetic field created induces a lower voltage in the secondary winding.

The process reduces the voltage while increasing the current proportionally. This is useful in applications where the power needs to be supplied at lower voltages for safety or efficiency reasons, such as in residential and commercial electrical systems.

By maintaining the same amount of power (ignoring losses), the reduction in voltage leads to a corresponding increase in current, making it an essential device for reducing voltages for practical usage in various electrical systems.
