What are the necessary and essential assumptions for an ideal transformer?

Which of the following characteristic assumptions for an ideal transformer are true?

An ideal transformer has infinite primary and secondary inductances. Explanation: The primary and secondary windings have zero resistance. It means that there is no ohmic power loss and no resistive voltage drop in the ideal transformer. An actual transformer has finite but small winding resistances.

Which condition is true for an ideal transformer?

An ideal transformer a transformer which has no copper losses, no iron loss in core and no leakage flux. In other words, an ideal transformer gives output power exactly equal to the input power.

Which one of these are the characteristics of a non ideal transformer?

Due to their non-ideal characteristics, these devices operate with a limited bandwidth, have insertion loss, a maximum power rating, and exhibit other frequency-, temperature- and power-dependent performance.

Which is not true for an ideal transformer?

The resistances of the primary and secondary winding are zero. The core of the ideal transformer has infinite permeability. The leakage flux in the transformer core is zero.

Which of the following statements about the ideal transformer features?

Explanation: Ideal transformer has constant permeability so that the magnetization of the core remains linear. 4. Which of the following statements support the ideal transformer features? Explanation: An ideal transformer should be free from all types of losses and must have a linear magnetization of the core material.

At what condition does an ideal transformer gives maximum efficiency?

The transformer will give the maximum efficiency when their copper loss is equal to the iron loss.

What is an ideal transformer give two sources of energy losses in a transformer and how such are reduced?

Two types of energy losses occur in transformers: Load and No-Load losses. Load losses result from resistance in the copper or aluminum windings. Load losses (also called winding losses) vary with the square of the electrical current (or load) flowing through the windings.
