Question

The losses in an ideal transformer will be:

• A. Zero
• B. Maximum
• C. Minimum
• D. Negative

Answer 1

The Correct Option is A

An ideal transformer serves as a theoretical construct for analytical purposes. It operates under the premise of perfect conditions, characterized by:
Absence of core losses (e.g., hysteresis and eddy currents),
Absence of copper losses (i.e., zero winding resistance),
Complete magnetic coupling (i.e., 100% flux linkage),
No leakage flux.Consequently, an ideal transformer exhibits output power precisely equal to its input power. This relationship is expressed as:[textEfficiency = fractextOutput PowertextInput Power times 100% = 100%]This signifies that losses are effectively zero. While practical transformers incur losses, the ideal model assumes lossless operation to simplify calculations.
