🔍 Key Concepts

• How a shunt field rheostat affects generator output voltage and current • Relationship between field current and generated voltage in a DC generator • What happens to field strength when resistance in the field circuit is changed

💭 Think About

• Think about whether you want more or less field current to get higher generator output • If you add resistance in series with the field, does current in the field winding go up or down? What does that do to the magnetic field? • For a machine already running normally, which choices are realistic operational adjustments versus extreme or impractical actions?

✅ Before You Answer

• Identify whether increasing field resistance makes the field current stronger or weaker • Decide if a stronger magnetic field produces higher or lower output voltage in a DC generator • Eliminate any options that would obviously reduce field strength or are not standard operating practice, like full shutdown for minor adjustments

Question 1 of 20

When increased output is desired from a motor-generator, what is the usual procedure?

Decrease the resistance after rheostat in series with the generator field

Increase the resistance of the rheostat in series with the generator field

Output cannot be easily increased

Shut down the motor-generator and restart under full load
