Solve u=I*R

$$u = I \cdot R$$

Solve for I (complex solution)

$$\left\{\begin{matrix}I=\frac{u}{R}\text{, }&R\neq 0\\I\in \mathrm{C}\text{, }&u=0\text{ and }R=0\end{matrix}\right.$$

Steps for Solving Linear Equation

Swap sides so that all variable terms are on the left hand side.

$$IR=u$$

The equation is in standard form.

$$RI=u$$

Divide both sides by R.

$$\frac{RI}{R}=\frac{u}{R}$$

Dividing by R undoes the multiplication by R.

$$I=\frac{u}{R}$$

Solve for R (complex solution)

$$\left\{\begin{matrix}R=\frac{u}{I}\text{, }&I\neq 0\\R\in \mathrm{C}\text{, }&u=0\text{ and }I=0\end{matrix}\right.$$
