A 34.7 meter long aluminum wire at a temperature of 24.3oC has a radius of 0.295 millimeter. If a potential difference of 15.6 Volt is applied across the length of the wire, compute the current in the wire. If the wire is heated to 76.8oC and the 15.6 Volts potential difference is maintained, compute the resulting current in the wire?
If the wire is heated to 73.8oC and the 19.2 Volts potential difference is maintained, compute the resulting current in the wire?
