**1. A conductive sheet of material has a CSA of 10mm x 20mm. Reisistivity of 10**

^{3 (10 to the 3, 10,000)}ohms M. Calculate thickness of the material required to give resistance of 5k ohms**2. Ro = RA/l , where l would be thickness, l = RA/Ro**

**3. Thickness = 5,000 x 0.2 / 10,000 = o.1m therefore 100m**
