Correct Answer: Alternating Current (AC) to Direct Current (DC)
Solution : The correct answer is Alternating Current (AC) to Direct Current (DC).
Alternating current (AC) is transformed into direct current (DC) using electronic devices called rectifiers. They achieve this by rectifying alternating current or limiting current flow to one direction. As many parts and circuits in electronic systems and gadgets run on DC power, this conversion is crucial.
