Choose true or false for each statement regarding the resistance of a wire. While maintaining a constant voltage V, the current I increases when the resistivity p of a wire decreases. O While maintaining a constant voltage V, the current I increases when the cross-sectional area A of a wire expands. The resistivity p is proportional to the resistance R of a wire. Submit Answer Tries 0/2 Choose true or false for each statement regarding resistors in a circuit. O Three identical resistors in series have one third the resistance of each individual one. 8 If you connect two different resistors in parallel in a circuit, then the current that flows through each of them is different. If you connect two different resistors in parallel in a circuit, then the voltage across each of them is different.
