3. If you change the resistivity of the resistor, is the effect like changing the length or changing the area? (answer, explain, evidence) 4. Resting the values of Length, Area, and Resistivity. If we were to double the cross-sectional area while keeping everything else constant, how would the resistance change? Provide values in your answer. Explain your
