Working with the variation of resistance in regards to temperature.
(a) A 5 m length of copper wire at 20°C has a radius of 0.25mm. If a potential difference of 10V is applied across the length of the wire, determine the current in the wire. (b) If the wire is heated to 50.0°C and the 10 V potential difference is maintained, what is the resulting current in the wire?
