3. a) A tungsten wire of length 20.0 m, initially at temperature 20.0°C, has a diameter of 2.00 mm. The potential difference across the whole wire is 180 V. Determine the current intensity in the wire b) Due to ohmic losses, the wire is heated up to 60.0°C, but the potential difference through the wire remains the same. Find the resulting current intensity. Note: po = 5,6x10 82 m, a=4.5x10(°C)
A cylindrical tungsten filament 15.0 cm long with a diameter of 1.10 mm is to be used in a machine for which the temperature will range from room temperature (20 ∘C) up to 120 ∘C. It will carry a current of 13.5 A at all temperatures ( Resistivity of tungsten at 20 ∘C is 5.25×10−8Ω⋅m , the temperature coefficient of resistivity at 20 ∘Cis 0.0045 ∘C−1 ) Part B What will be its resistance with that field?
