\nA) A split-ring type commutator is the correct component needed to convert an AC generator into a DC generator.
\n<\/section>\n
\n– An AC generator produces alternating current due to the use of slip rings, which maintain continuous contact with the rotating coil.
\n– To convert this to direct current (DC), the direction of the current in the external circuit needs to be maintained constant.
\n– A split-ring commutator achieves this by reversing the connection of the coil to the external circuit every half rotation, ensuring that the current flows in the same direction in the external load.
\n<\/section>\n
\n– Slip rings are used in AC generators to connect the armature coil to the external circuit.
\n– A stronger magnetic field would increase the magnitude of the induced electromotive force (EMF) and current, but would not change the nature of the output from AC to DC.
\n– A rectangular wire loop is the armature coil, which is a component of both AC and DC generators. The type of output depends on how the coil is connected to the external circuit (via slip rings for AC, or a commutator for DC).
