Which component provides two equal voltages to a conventional full-wave rectifier?

A center-tapped transformer is the component that provides two equal voltages to a conventional full-wave rectifier. In this configuration, the transformer has a tap at its center winding, which allows it to deliver two equal voltage outputs that are 180 degrees out of phase with each other. This results in a full-wave rectification process where both halves of the AC waveform are utilized, effectively doubling the available output voltage and improving efficiency.

Using a center-tapped transformer provides the necessary voltage levels required for the full-wave rectifier to effectively convert AC to DC. The two voltages produced by the center tap serve as inputs to the rectifier, allowing it to use both halves of the AC cycle, thus producing a smoother and more reliable DC output compared to a half-wave rectification method. This is essential for various applications where stable and uninterrupted power supply is critical.
