A second experiment can be carried out to investigate experimentally how the resistance of a metallic conductor at constant temperature depends on the area of cross section. The above experiment ...
LEVITT 1 directly compares a resistance for flow of liquid water ... an equivalent air path ; this is a tube of air of unit cross-sectional area of such a length that, with the equivalent ...
