Answer Details
To convert an alternating current (AC) dynamo into a direct current (DC) dynamo, you need to replace the slip rings with a split-ring commutator. Slip rings allow the current to change direction every half-turn, resulting in an AC current output. However, a split-ring commutator ensures that the current flows in the same direction at all times, creating a direct current output. The number of turns in the coil, strength of the field magnet, and the material of the armature do not affect the conversion from AC to DC.
