\textbf{187-} The electrical resistance of a wire is $6\,\Omega$. We cut $\dfrac{3}{4}$ of the wire and set it aside, and connect $\dfrac{1}{4}$ of the remaining wire to the device, stretching it until its length equals the original wire's length. With temperature held constant, what is the resistance of the new wire?
