Activity 1 and 2: Resistivity and Conductivity Directions: Copy and complete the table below. Use the terms increase and decrease. Write the answer on your answer sheet. Effect on Resistance Effect on Current Flow Electrical Resistivity Decrease Higher Tent erature p Lower Length of the conductor Longer Cross-sectional area of conductor Source: Oliver MDavidJ! 7.Generaf Physics 2.Phihppines: University Press First Asia Guided Questions 1. Would increasing the resistivity decrease the resistance through an electrical cord? Explain 2. Would increasing the length of the cord decrease the resistance through an electrical cord? Explain 3. Would increasing the cross-sectional area of the cord decrease the resistance through an electrical cord? Explain 4. By how much will resistance change if resistivity and length are constant, and cross-sectional area is doubled? Explain
