A metal wire of resistance $R$ is cut into two pieces of equal length. The two pieces are connected together side by side. What is the resistance of the two connected wires?
Added by Sabrina G.
Step 1
Step 1: The resistance of a wire is given by the formula $R = \rho \times \frac{L}{A}$, where $\rho$ is the resistivity of the material, $L$ is the length of the wire, and $A$ is the cross-sectional area of the wire. Show more…
