Several cylindrical resistors are manufactured from the same uniform metal. Two different lengths of resistor are available, and each length is available in two different cross-sectional areas.
Which resistor has the lowest electrical resistance?
the resistor with the greater length and the larger cross-sectional area
the resistor with the greater length and the smaller cross-sectional area
the resistor with the smaller length and the larger cross-sectional area
the resistor with the smaller length and the smaller cross-sectional area
