Three types are
- self inductance
- mutual induction
- dot notation
- It is stores energy in a magnetic flux field.
VL=L di/dt ,where is an inductor.
- we have applied to current one coil change flux in the first coil links the adjacent coil linking changing flux induced a voltage in the second coil as per Faraday's law.[ unit is hentry (H) ]
- Dot on the coils indicate the polarity of voltage induced in the coils.
