Wire sizes are often reported using the AWG (American Wire Gauge) system in which smaller diameter wires are said to be of higher gauge. Thus the thin 24-gauge wire included in many electronics kits has a wire diameter of 0.51 mm, while a thicker 12-gauge wire used for many home audio speakers has a wire diameter of 2.05 mm. Different gauge wires have different maximum current ratings, with thicker wires being capable of safely handling larger current.

A. Consider a meter of 24-gauge copper wire. Calculate the resistance of this wire.

B. Imagine that this 1-meter length of 24-gauge copper wire were laid across the terminals of an ideal 12-volt battery. Calculate the current that would run through the wire.

C. The maximum safe current rating for 24-gauge copper wire is 2.0 Amps. What is the shortest length of this wire that could be safely placed across the ideal 12-volt battery?
