Solve u=R/I

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

Solve for I

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

Steps for Solving Linear Equation

Variable I cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by I.

$$uI=R$$

Divide both sides by u.

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

Dividing by u undoes the multiplication by u.

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

Variable I cannot be equal to 0.

$$I=\frac{R}{u}\text{, }I\neq 0$$

Solve for R

$$R=Iu$$

$$I\neq 0$$

Solution Steps

Multiply both sides of the equation by I.

$$uI=R$$

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

$$R=uI$$
