Which of the following characteristics reveal about the magnetization ...
Magnetization nature of a machine refers to the ability of a machine to produce a magnetic field when an electric current is passed through it. The characteristics of a machine, such as its no-load and load characteristics, provide information about its magnetization nature.
No-Load Characteristics:
The no-load characteristic of a machine refers to the relationship between the generated voltage and the field current when the machine is running at no load. In other words, it is the open-circuit characteristic of the machine. The no-load characteristic reveals the magnetization nature of the machine as it indicates the amount of magnetic flux produced by the machine at no load.
Load Characteristics:
The load characteristic of a machine refers to the relationship between the generated voltage and the load current when the machine is running at a load. The load characteristic provides information about the magnetization nature of the machine as it indicates the amount of magnetic flux produced by the machine under load conditions.
Armature Characteristics:
The armature characteristic of a machine refers to the relationship between the armature current and the generated voltage when the field current is kept constant. The armature characteristic provides information about the performance of the machine, but it does not reveal much about the magnetization nature of the machine.
Both No-Load and Load Characteristics:
Both the no-load and load characteristics of a machine provide information about the magnetization nature of the machine. The no-load characteristic indicates the amount of magnetic flux produced by the machine at no load, while the load characteristic indicates the amount of magnetic flux produced by the machine under load conditions. Together, these characteristics provide a comprehensive understanding of the magnetization nature of the machine.
In conclusion, the correct answer to the question is option 'D' as both the no-load and load characteristics reveal information about the magnetization nature of the machine.
