A square rod and a cylindrical rod are made of the same copper alloy and cut to the same length, as shown in the figure. When a potential difference of 1.70 V is applied across the length of cylindrical rod, it dissipates 10.0 W by heating. What voltage should be applied across the length of the square rod so that it also dissipates 10.0 W.
