Question

R= V/I Solve for I and Solve for V

Answer 1

We have the next formula

`R=(V)/(I)`

And we must solve it for I and for V.

1. Solving the formula for I

`\begin{gathered} R\cdot I=(V)/(I)\cdot I \\ (1)/(R)\cdot R\cdot I=V\cdot(1)/(R) \\ \text{ So, the formula for I is:} \\ I=(V)/(R) \end{gathered}`

2. Solving the formula for V

`\begin{gathered} R=(V)/(I) \\ R\cdot I=(V)/(I)\cdot I \\ \text{ So, the formula for V is} \\ V=R\cdot I \end{gathered}`
