Question 1 of 27070

By what means is DC generator output voltage decreased?

🔍 Key Concepts

• Relationship between field current, magnetic flux, and generated voltage in a DC generator • Effect of field resistance vs armature resistance on terminal voltage • Which part of the circuit is normally used to control or regulate generator output

💭 Think About

• If you want less output voltage, do you want more or less magnetic field strength? • Which change (field resistance or armature resistance) most directly changes the magnetic field produced by the generator? • Think about what a generator voltage regulator actually adjusts in practice—field circuit or armature circuit?

✅ Before You Answer

• Be clear on Ohm’s Law in the field circuit: higher resistance → lower current → weaker field • Distinguish between changes that affect generated EMF (inside the machine) and those that mainly cause voltage drop under load • Focus on which adjustment is the standard method used to control DC generator output voltage in real installations
