Material 1 0.00591 2 m Three resistors are made out of three different materials and have different (but uniform) cross sections. Resistor 1 Material 2 0.682 2 m has a circular cross section of radius 2.04 mm. Resistor 2 Material 3 2.39 x 10 2 m -5 has a square cross section with a side length of 2.22 mm. The third resistor's cross section is a right triangle with two sides of length 6.47 mm. All of the resistors are 0.538 cm 3 in length. Use the provided table of resistivities to calculate the resistance of each resistor.

When unequal resistors are connected in parallel in a circuit, a the same current always runs through each resistor. b the potential drop is always the same across each resistor. c the largest resistance has the largest current through it. d the power generated in each resistor is the same.

Two cylindrical resistors are made from the same material and are equal in diameter. The first resistor has length L, and the second resistor has length 2L. If the same current flows through both, compare the voltage across the two resistors:    V1 > V2   V1 = V2   V1 < V2   none of the above
