Vyjadrenie veličiny R2 zo vzorca
Vyjadri zo vzorca \( R=R_{1}+\frac{R_{2} R_{3}}{R_{2}+R_{3}} \) veličinu \( R_{2} \).
\( R_{2}=\frac{R_{3}\left(R_{1}-R\right)}{R+R_{1}+R_{3}} \)
\( R_{2}=\frac{R_{3}\left(R_{1}+R\right)}{R-R_{1}+R_{3}} \)
\( R_{2}=\frac{R_{3}\left(R_{1}-R\right)}{R-R_{1}-R_{3}} \)
\( R_{2}=\frac{R_{3}\left(R_{1}+R\right)}{R+R_{1}-R_{3}} \)
