Question

Which of the following statements are true about an electric resistance? List all that apply.

The resistance of an electric circuit is a measure of the overall amount of hindrance to the flow of charge through the circuit.
A large resistance value indicates that the charge is encountering a relatively large amount of difficulty in moving through the circuit.
The unit of resistance is the ampere.
A 5-ohm resistor would allow a current of 0.5 Amperes when 2.5 Volts is impressed across it.
A 10-ohm resistor would allow a current of 2 Amperes when 5 Volts is impressed across it.
The resistance of a conducting wire will increase as the length of the wire is increased.
The resistance of a conducting wire will increase as the cross-sectional area of the wire is increased.
Increasing the resistance of an electric circuit will cause the current in the circuit to increase.
A threefold increase in the resistance of an electric circuit will result in a threefold decrease in the electric current.
A miniature light bulb with a specific resistance is connected to a 1.5-Volt battery to form a circuit. If it were connected to a 6-Volt battery instead, its resistance would increase by a factor of 4.
