Namealex D Resistance WS date 1. Write the equation for the resistance of metals that involves resistivity, length and cross-sectional area. R = Sketch the graphs of R vs. p, R vs. L and R VS. A. R R R L A How is R related to r? How is R related to L? How is R related to A? a/ Describe how the resistance, R, of a wire would change if you doubled its length. If you tripled its length. If you halved its length. b / Describe how the resistance of a wire would change if you doubled its resistivity. If you tripled its resistivity. If you halved its resistivity. c/ Describe how the resistance of a wire would change if you doubled its cross-sectional area. If you tripled its cross-sectional area. If you halved its cross-sectional area. d/ Describe how the resistance of a wire would change if you.... ...doubled both its length and its area? ..halved its length and its area? ...halved its length but doubled its area? ...doubled its diameter (or radius)? ...doubled its diameter and its length
