( I = p r t )
Solve for p (complex solution)
\left\{\begin{matrix}p=\frac{I}{rt}\text{, }&t\neq 0\text{ and }r\neq 0\\p\in \mathrm{C}\text{, }&\left(t=0\text{ or }r=0\right)\text{ and }I=0\end{matrix}\right.
Solve for p
\left\{\begin{matrix}p=\frac{I}{rt}\text{, }&t\neq 0\text{ and }r\neq 0\\p\in \mathrm{R}\text{, }&\left(t=0\text{ or }r=0\right)\text{ and }I=0\end{matrix}\right.
Solve for I

prt=I
Swap sides so that all variable terms are on the left hand side.
rtp=I
The equation is in standard form.
\frac{rtp}{rt}=\frac{I}{rt}
Divide both sides by rt.
p=\frac{I}{rt}
Dividing by rt undoes the multiplication by rt.
