Choose true or false for each statement regarding the resistance of a wire. The resistivity does not depend on the temperature of most metal wires. While maintaining a constant voltage V, the current I increases when the resistivity p of a wire increases. While maintaining a constant voltage V, the current I decreases when the cross-sectional area A of a wire contracts. Submit Answer Tries 0/2 Choose true or false for each statement regarding resistors in a circuit. Three identical resistors in series have triple the resistance of each individual one. If you connect two different resistors in parallel in a circuit, then the voltage across each of them is different. If you connect two different resistors in series in a circuit, then the current that flows through each of them is different. Submit Answer Tries 0/2

Complete the following statement: The sum of the magnitudes of the currents directed into a junction equals the sum of the magnitudes of the currents directed out of the junction. equals the current that is directed along one of the lines out of the junction. O is divided equally among the number of lines directed out of the junction. O is greater than the total current directed out of the junction. O is less than the total current directed out of the junction.
