Question
A rod of length 2.3 m, with a rectangular cross section (1.5mm x 3.0 mm) is made of
a material with a resistivity of 6.1 × 10^-8 Ohm. A potential difference of 5.0 V is
places across the ends of the rod.
a. Draw a clear physics diagram of the problem.
b. At what initial rate is heat generated in the rod?
c. Will the rate from part (b) increase, decrease, or remain constant
over time, as the rod remains connected to the 2.5 V potential difference?
