is transformer, active or passive device?
name some active and passive devices.
Answer Posted / hariohm kumar
Transformer is a passive device..Active device is that which
has the ability to electrically control(control AC using DC)
flow of electrons.
But transformer has not such type of ability.
Example:-Active-Transistor,SCR,TRIACs etc.
Passive-Resistors,capacitors,inductors,transformers,Diodes etc.
