Question: #3a: A rod in the shape of a rectangular solid has a cross-sectional area of 15.8 cm, a length of 5.20 cm and a resistivity

#3a: A rod in the shape of a rectangular solid has a cross-sectional area of 15.8 cm, a length of 5.20 cm and a resistivity of 15.8 x10 8 ohm.m. The material of which the block is made has 5.95 x 1028 conduction electrons/m. A potential difference of 52.6 mV is maintained between its ends. What is the current in the block? Put your answer in the form of "a.bc x 10^& A". Answer: #3b: Assume that the current density in the previous problem is uniform. What is of its value? Put your answer in the form of "a.bc x 10^(x) A/m^(2)". stion to search O 61.F Mostly sunny
