Choose true or false for each statement regarding the resistance of a wire.
true false  While maintaining a constant voltage V, the current I increases when the cross-sectional area A of a wire expands.
true false  While maintaining a constant voltage V, the current I increases when the resistivity ρ of a wire decreases.
true false  The resistivity ρ is proportional to the resistance R of a wire.

Choose true or false for each statement regarding resistors in a circuit.
true false  If you connect two different resistors in series in a circuit, then the current that flows through each of them is different.
true false  Three identical resistors in series have one third the resistance of each individual one.
true false  If you connect two different resistors in series in a circuit, then the voltage across each of them is the same.
