Electronics Fundamentals/Passive Components/Inductor

Inductor is an electronic component made from a straight wire conductor with several turns of the dimension Length l , Area A , Number of Turns N and Permitivity of u

${\displaystyle L=\mu N^{2}{\frac {l}{A}}}$

B = L I

${\displaystyle I={\frac {B}{L}}}$

${\displaystyle L={\frac {B}{I}}}$

${\displaystyle v=L{\frac {di}{dt}}}$

${\displaystyle i={\frac {1}{L}}\int vdt}$

${\displaystyle X=\omega L\angle 90}$

${\displaystyle X=j\omega L}$

${\displaystyle X=sL}$

${\displaystyle Z=R\angle 0+\omega L\angle 90}$

${\displaystyle Z=R+j\omega L}$

${\displaystyle Z=R+sL}$

${\displaystyle Tan\theta =\omega {\frac {L}{R}}=2\pi f{\frac {L}{R}}=2\pi {\frac {T}{t}}}$
