TransformersQuestion 1113 of 1506

A transformer is tested with a resistive load and with an inductive load of the same current. Which statement is correct?

  1. The inductive load tends to give better regulation than the resistive load.
  2. The inductive load tends to give worse regulation.
  3. Both load types give exactly the same regulation figure.
  4. Regulation does not depend on the type of load at all.
Show answer

Correct answer: The inductive load tends to give worse regulation.

The resistive test is a best-case condition. Inductive loads make voltage regulation worse.
