1. What is the resistance of a 100-m length of #22 AWG
copper conductor?
2. An undetermined number of metres have been used from a carton
of#14 AWG wire. If the measured resistance is 1.6 2, determine
the length of wire remaining in the carton.
3.If the resistance of a copper wire is 50 2 at 20°C, what is its
resis-tance at 100°C (boiling point of water)?
4.If the resistance of a copper wire at freezing (0°C) is 30 N, what
is its resistance at -40°C?
5.If the resistance of an aluminum wire at room temperature (20°C)
is 100 m2 (measured by a milliohmmeter), at what temperature will
itsresistance increase to 120 mN?
