AP Physics C: E&M
11.3 Resistance, Resistivity, and Ohm’s Law
Two cylindrical resistors, Resistor 1 and Resistor 2, are made of the same uniform material. Resistor 1 has length \(L_0\) and cross-sectional radius \(r_0\). Resistor 2 has length \(8L_0\) and cross-sectional radius \(2r_0\). What is the ratio \(\dfrac{R_2}{R_1}\) of the resistance of Resistor 2 to the resistance of Resistor 1?
