Three resistors are made out of three different materials and Material 1 0.00479 Q·m have different (but uniform) cross sections. Resistor 1 has a Material 2 0.391 N·m circular cross section of radius 1.18 mm. Resistor 2 has a Material 3 6.87 x 10-5 2-m square cross section with a side length of 1.37 mm. The third resistor's cross section is a right triangle with two sides of length 6.47 mm. All of the resistors are 0.838 cm in length. Use the provided table of resistivities to calculate the resistance 3 2 of each resistor.
