Q

How are AC and DC generators similar?

🔍 Key Concepts

• Basic generator principle: how voltage is induced when a conductor cuts magnetic lines of flux • Difference between how power is generated inside the machine vs. how it is delivered to the circuit • Role of commutators and rectifiers in DC machines

💭 Think About

• Think about what physically happens in the armature windings as they rotate in a magnetic field — is that AC or DC inside the windings? • Ask yourself whether three-phase power or 60 cycles (60 Hz) are required features of all generators, or just common in certain applications. • Consider whether rectification (changing AC to DC) happens in both AC and DC generators, or only in one type.

✅ Before You Answer

• Verify what type of voltage is induced in the rotating conductors of both AC and DC generators before any commutator or external circuitry is involved (internal generation). • Check whether three-phase and 60 cycles are universal characteristics or just typical for certain power systems. • Confirm which machine(s) actually use a commutator or rectifier to change the internally generated voltage before it’s supplied to the load.
