Inductor       03/07/16

 

Inductors are some of the most fundamental components of the modern day circuit. An inductor usually consists of conducting wire wrapped into a coil, and since a current will run through this wire, a magnetic field will be produced. As a result of Maxwell’s equations, the energy stored in the magnetic field will try to oppose any change in current and a voltage will be created in the inductor. The strength of an inductor is measured by it’s inductance. Inductance is defined as L=i, with Lbeing the inductance , being magnetic flux and ibeing the current. The voltage across an inductor can be symbolically derived by faraday’s law of inductance v=ddtwhich by using substitution leads to v(t) =L*didt. Inductors are widely used to tune out certain frequencies
