Question
The resistance of a wire at constant temperature depends on the wire's(A) length, only(B) type of metal, only(C) length and cross-sectional area, only(D) length, cross-sectional area, and type of metal
Step 1
Step 1: The resistance of a wire is given by the formula: \[ R = \rho \frac{L}{A} \] where \( R \) is the resistance, \( \rho \) is the resistivity (which depends on the type of metal), \( L \) is the length of the wire, and \( A \) is the cross-sectional area of Show more…
