Q1. Losses in transformer
Ans. 
Losses in transformer refer to energy losses that occur during the conversion of electrical energy from one voltage level to another.
• There are two main types of losses in transformers: copper losses and iron losses.

• Copper losses occur due to the resistance of the copper windings and are also known as I^2R losses.

• Iron losses, also known as core losses, occur due to hysteresis and eddy current losses in the transformer c...read more
