* Introduction
The name is a misnomer; Ohm's law simply refers to the tendency for real world materials to obey this relation:
\begin{align}
\label{}
V = IR
\end{align}
where $V$ is the [[id:951db9ac-3e8b-49a1-b609-2bbb795be834][voltage]], $I$ is the current, and $R$ is a proportionality constant arguably defined by this equation.
Essentially this law posits that resistors scale the current in a [[id:ab024db7-6903-48ee-98fc-b2a228709c04][linear]] fashion. This law is used extensively in
the analysis of resistors in [[id:a7d6d6e9-9f7a-446f-b6af-255c802f86b1][circuit analysis]].
