Transformer — principle?
Operates on mutual induction between coils.
Transformer losses — main?
Iron (core) and copper (winding) losses.
Slip — in induction motor?
Difference between synchronous and rotor speed.
Transformer — primary function?
Transfer electrical energy via electromagnetic induction.
Mutual Induction — role?
Induces voltage in secondary coil.
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.
