Transformer — principle?

Operates on mutual induction between coils.

Transformer — primary function?

Transfer electrical energy via electromagnetic induction.

Transformer losses — main?

Iron (core) and copper (winding) losses.

Mutual Induction — role?

Induces voltage in secondary coil.

Slip — in induction motor?

Difference between synchronous and rotor speed.

Self Induction — difference from mutual?

Induction caused by own changing current.

Core Material — purpose?

Reduces eddy current losses.

Iron Loss — components?

Hysteresis and eddy current losses.

Efficiency — maximized when?

Copper loss equals iron loss.

Transformer — AC or DC?

Only works with AC.
