Section 29.2 Inductors
Definition 29.2.1. Inductor.
An
inductor is a wire coil
1 used as a circuit element. The voltage across an inductor is given by
\begin{equation*}
V_{inductor} = -L \frac{dI}{dt}\text{.}
\end{equation*}
Here, \(L\) is the inductance and it is measured in Henries (H). Inductors can also store energy given by \(U_L = \frac{1}{2} L I^2\text{.}\)
