What is the current in the block

Reference no: EM13294991

A 5.78 cm long rod in the shape of a rectangular solid has cross section dimensions 28.7 mm x 42.6 mm. The material of which the block is made has 5.95 x 1028 conduction electrons per cubic meter and conductivity = 1.28 x 107 (Ohm-meter)-1 . A potential difference of 15.0 mV is maintained between its ends. What is the current in the block? Put your answer in the form of "a.bc A".
