The \(\textit{ohm}\) is the SI derived unit of electrical resistance, named after German physicist Georg
Simon Ohm. It is defined as: \[\Omega \equiv\ \frac{\text{V}}{\text{A}}\ \equiv\
\frac{\text{volt}}{\text{amp}}\ \equiv\ \frac{\text{W}}{\text {A}^{2}}\ \equiv\
\frac{\text{watt}}{\text{amp}^{2}}\ \equiv\ \frac{\text{H}}{\text {s}}\ \equiv\
\frac{\text{henry}}{\text{second}}\]
