The temperature of coefficient of resistance of
copper at 0°C is 0.004626/°C. If the tip to tip of a
conductor is 110 milli ohm at 0°C, to what value will
the resistance increases at a temperature of 80°C?
Determine the thermal coefficient of resistance of copper at 50°C, then use this value todetermine the resistance of copper wire at 170° if the resistance of this copper wire at 50°C is50ohms. The thermal coefficient of resistance of copper at O°C is 0.004264/C°
10) A certain batch of copper wire was found to have a conductivity
of 98% at 20°C. What is its resistivity in uQ-cm?
