Understand the Problem
यह प्रश्न एक D.C. जनरेटर से संबंधित अवधारणाओं और सूत्रों के बारे में जानकारी मांग रहा है। यह पाठ्यक्रम से संबंधित प्रश्नों का एक सेट प्रतीत होता है, जिसमें विभिन्न तकनीकी विवरण और गणनाएँ शामिल हैं।
Answer
1. E = (PΦZN/60A), 2. Pole shoe, 3. Varies, 4. Fleming's right-hand rule, 5. Commutator converts AC to DC.
- The formula to calculate the generated emf (E) in a D.C. generator is E = (PΦZN/60A). 2. The part marked 'X' in a DC generator is typically a 'Pole shoe'. 3. The name of the D.C. generator can vary based on configuration but it's not specified in the image. 4. Fleming's right-hand rule is used to find the direction of current in a D.C. generator. 5. A D.C. generator needs a commutator to convert the alternating current generated inside the armature to direct current for external circuits.

More Information
Generated emf in a D.C. generator can be calculated using P (number of poles), Φ (flux per pole), Z (total number of armature conductors), N (speed in RPM), and A (number of parallel paths).
Tips
Remember that the commutator is essential in a DC generator to ensure the output remains DC as the armature naturally generates AC.
