Physics is a cumulative subject, so make it sure that you understand basic concepts and typical problem solving techniques in previous chapters before moving on to a new chapter. ________________________________________________________________________________ A. Resistance & Resistivity Two conductors are made of the same material and have the same length. Conductor A is a solid wire of diameter 5.00 mm. Conductor B is a hollow tube of outside diameter 6.00 mm and inside diameter 3.00 mm. What is the resistance ratio R A /R B , measured between their ends? B. Equivalent Resistance In the figure below right, R 1 = 6 , R 2 = 3 and R 3 = 4 . Find the equivalent resistance of the combination of the five resistors. C. Kirchoff’s Rules
