Copper has a resistivity (Ω) of 1.68 x 10-8 Ohm-m. A resistor iscreated from the rectangular prism shown in the figure to theright. Consider creating a resistor by contacting either side A andside B OR side C and side D.
The prism has a height (h)of 0.01 um.

a) What is the sheet resistance of the copper? Hint: You don’tneed a calculator
b) To make a resistor of 168 Ohms between sides A and B, findthe length (l) if the width (w) is 1 um? Find the resistancebetween sides C and D.
c) As discussed in class, a resistor dissipates
