The figure below displays the shape of a variable cross-section resistor made out of a conductive material with the resistivity p-3.2 x 10- n-m. This resistor was cut out of a material plate of thickness h=1.26 mm and has a variable width, changing lineartly from a=6.9 mm at one end to b=17 mm at the other end. Its length along the current direction is m40.9 cm. Find reistance Rof this resistor: m. R- If the voitage aeross this resistor V1.1 V, what is the strength E of the driving electric field in the "middle" cross-section of width (a+b/2=4.3 mm?: E- V/m.
