+\subsection{オームの法則}
+
+ある抵抗値を持つ抵抗器$R \ [\Omega]$に対し電圧$V \ [\text{V}]$を印加すると抵抗に電流$I \ [\text{A}]$が流れる．
+この時，$V, R, I$には次の関係式が成り立つ．
+
+\begin{equation}\label{equ:ohm}
+    V = RI
+\end{equation}
+
+\cref{equ:ohm}で表されるこの関係をオームの法則という．
+
+電圧は電流に比例するのでV-I図は\cref{fig:v-i-example}のようになる．

+\subsection{キルヒホッフの法則}
+
+複数の抵抗・電源からなる複雑な回路はオームの法則だけでは回路を解くことはできない．
+キルヒホッフの法則はそのような回路網を計算する際に用いられる．
+
+この法則には2つの性質が定義されている．
+
+第一法則は電流則とも呼ばれ，回路中の接点の電流の入出流の関係が定義されている．
+
+第二法則は電圧則とも呼ばれ，
