Potential difference across the terminals of the wire

Reference no: EM132048235

Examine the dependence of resistivity and resistance of a wire on temperature and how it affects the potential difference across the terminals of the wire.

A current of 60 mA flows through a wire of length L= 1.65 m long and diameter of d=1.1 mm at a temperature of T₀= 20 °C; the wire's resistivity at this temperature is ρ₀= 5.33×10^-8 Ω · m. The coefficient of resistivity of the material is α= 4.6×10^-3/C

What is the resistance of the wire at 20 °C?

What is the potential difference across the ends of this wire at 20°C in milli-volts (mV) ?

If the wire temperature increases to 106C°, what potential difference (in mV) across its ends is now required to produce a current of 60 mA?
