🔍 Key Concepts

• Basic operating principle of AC and DC generators (what happens in the rotating coil in a magnetic field) • Difference between what is generated internally in the armature vs. what is delivered externally at the terminals • Role of rectification/commutation in DC machines

💭 Think About

• Think about the voltage induced in a conductor moving in a magnetic field. Is that voltage naturally AC or DC inside the machine? • In a DC generator, what component changes the internal voltage/current so that the output appears DC at the terminals? • Which options talk about what happens inside the generator vs. what you see at the output of the generator?

✅ Before You Answer

• Identify which option correctly describes the internal generation process in both AC and DC generators, not just the output form • Verify whether DC generators need rectifiers like electronic diodes, or use a different mechanical method to get DC at the output • Check if the statement about physical size vs. kW rating is always true, or if it can vary with design and cooling methods
