An inductor is a bunch of wires wound in such a way their electromagnetic fields interact. When the current flowing through the coil changes, the time-varying magnetic field induces a voltage that opposes the change in current that created it.
An inductor is a bunch of wires wound in such a way their electromagnetic fields interact. When the current flowing through the coil changes, the time-varying magnetic field induces a voltage that opposes the change in current that created it. If there is no change in current flowing through the coil, then the steady state response of an inductor matches that of a short circuit/wire.
An inductor is *dual* to a capacitor.
- $v(t) = L \frac{d I}{d T}$
- $i(t) = \frac{1}{L} \int_0^t v(\tau) d \tau$
