If you must adjust generator __________, always work with the series field.

If you must adjust generator __________, always work with the series field.

• A. Regulation
• B. Compounding
• C. Excitation
• D. Speed

Answer: (B)

Compounding controls how much of the series-field flux is added to the shunt-field flux to shape the generator’s voltage change from no-load to full-load. The series field carries current that varies with the output, so its flux directly affects how the voltage rises or falls under load. By adjusting the series field, you change the amount of flux contributed during operation, which is how you set the compound action and voltage regulation. The shunt field is kept constant so you don’t disturb the baseline excitation, making the series field the correct focus for adjusting compounding.
