Question

Three resistors are made out of three different materials and have different (but uniform) cross-sections Resistor 1 has a circular cross-section of radius 1.61 mm. Resistor 2 has a square cross section with a side length of 3.92mm. The third resistor's cross-section is a right triangle with two sides of length 1.62 mm as shown. All of the resistors are 0.538 cm in length. Use the provided table of resistivities to cakculate the resistance of each resistor Material 1 Material 2 Material 3 | 5.91x103 Ω.m |0585 Ω-m |3.51 x 105 Ω-m Number }1.61 ㎜ Number R,= 3.92 mm Number 31.62 mm
