Voltage regulation of an alternator when connected to inductive load

by

Voltage regulation of an alternator when connected to inductive load:

  1. Positive
  2. Negative
  3. Zero
  4. None of these

Correct answer: 1. Positive

Formula for Voltage Regulation:

Whenever some inductive load is added to the alternator (AC generator) the terminal voltage decreases. In simple words for lagging (inductive or loads having +Q) are added to generator the V(FL) < V(NL) and thus the voltage regulation is positive.
