Questions & Step-by-Step Solutions
Which of the following losses is predominant in a transformer?
Step 1: Understand that transformers are electrical devices that transfer energy between circuits using electromagnetic induction.
Step 2: Learn about the types of losses that occur in transformers: copper loss and iron loss.
Step 3: Copper loss (I²R loss) happens due to the resistance in the wires when current flows through them.
Step 4: Iron loss consists of two parts: hysteresis loss, which occurs due to the magnetization and demagnetization of the iron core, and eddy current loss, which is caused by circulating currents in the core.
Step 5: Compare the two types of losses. Copper loss is related to the current flowing through the wires, while iron loss is related to the core material.
Step 6: Conclude that while both losses are important, iron loss is often more significant in transformers.
