A \( 5 \Omega \) resistor and a variable resistor of resistance \( R \) are placed in parallel. The expression for the resulting resist given by \( R_{T}=\frac{5 R}{5+R} \). Determine the limiting value of \( R_{T} \) as \( R \rightarrow \infty \). The limiting value of \( R_{T} \) is (Simplify your answer.)
