उत्तर
Electrolysis is caused by DC.
Explanation:
Electrolysis is a chemical decomposition process that relies strictly on direct current (DC). Direct current flows in only one direction, maintaining fixed positive and negative polarities at the electrodes (anode and cathode), which allows specific ions to migrate consistently toward them and discharge. Alternating current (AC) is unsuitable because it rapidly reverses direction, constantly swapping electrode polarities and causing ions to alternate directions, preventing meaningful chemical separation or deposition.
