A 3.50-meter length of wire with a crosssectional

area of 3.14 × 10^–6 meter2 is at

20° Celsius. The current in the wire is

24.0 amperes when connected to a 1.50-volt

source of potential difference.

Determine the resistance of the wire.

Resistance = (voltage) / (current)  

                         (1.5 V) / (24 A)  =  0.0625 ohm.

All that business about the description of the conductor ...
its length, size, temperature, color, price, etc. ... is only
there to distract and confuse us.  It's all irrelevant.
