Question

3. The areal resistivity of the carbon-impregnated paper you used in this experiment is about 10.000 2. Explain what this statement means, showing in particular why the units of areal resistivity are the same as the units of resistance between the terminals of a conductor 4. Show why the field berween two large but closely spaced parallel plates carrying equai but opposite charges should be uniform in the region not too near the edges. Use any method you can understand and explain. s. Derive a relation between the potential V and the magnitude of the field E at a radial dist the axis of a very long uniformly charged rod of radius a (r>a). ance r from
