R=(I)/(PT)

Step-by-step explanation


I=\text{PRT}

Step 1

divide both sides by P


\begin{gathered} I=\text{PRT} \\ (I)/(P)=(PRT)/(P) \\ (I)/(P)=RT \end{gathered}

Step 2

divide both sides by T


\begin{gathered} (I)/(P)=RT \\ (I)/(PT)=(RT)/(T) \\ (I)/(PT)=R \\ R=(I)/(PT) \end{gathered}

I hope this helps you
