(b) A resistor made of a carbon rod has uniform cross-sectional area of 5.0 mm When a potential difference of 15.0 V is applied across the ends of the rod, the rod carries a current of 4.0 mA. The resistivity of carbon is 3.5 x 10-50m. Calculate the (1) resistance of the rod (ii) length of the rod. [4 marks
