The d.c generator has essentially the same components as the a.c generator except the presence of?
Answer Details
The statement is talking about the components of a DC generator, which is a device that converts mechanical energy into electrical energy. It says that a DC generator has the same components as an AC generator, which is a device that generates alternating current (AC) electricity, except for the presence of one specific component. The component that is absent in the DC generator is the slip-ring, which is present in the AC generator. Slip-rings are used to transfer electrical power from a rotating part (such as the rotor in a generator) to a stationary part (such as the stator), while still allowing the rotating part to spin freely. In a DC generator, however, the electrical power is transferred through the use of carbon brushes that make contact with a split-ring commutator mounted on the armature. So, the answer is "slip-ring".
