A copper wire with a length of 5 meters and a cross-sectional a 10−6 m² has a resistivity of 1.68 × 10-8 № · m. Calculate the copper wire. 2. Resistor Temperature Dependence: The resistance of a tungsten filament in an incandescent light b room temperature. If the temperature of the filament increases becomes 75 ohms, calculate the percentage increase in resista
