How are AC and DC generators similar?

🔍 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

How are AC and DC generators similar?

They both internally produce three-phase power.

They both internally generate alternating current voltages.

They both rectify the current before delivery.

They are both constructed at the same physical size for the same kilowatt rating.
