Calculating Resistance of Copper Conductor at High Temperatures - советы от нейросети

Сопротивление медного проводника при 0°С равно 10.Ом.Определите сопротивление этого проводника в Омах при 500°С. (α=0,004К^-1)

The resistance of the copper conductor at 0°C is 10Ω. To determine its resistance at 500°C, we can use the formula R = R0(1 + αΔT), where R is the resistance at the given temperature, R0 is the resistance at the reference temperature of 0°C, and α is the temperature coefficient of resistance. In this case, our reference temperature is 0°C and our given temperature is 500°C. Therefore, we can plug in the values and solve for the resistance at 500°C: R = 10Ω(1 + 0.004K^-1 * (500°C - 0°C)). This gives us a resistance of 12Ω. This increase in resistance is due to the increase in temperature, which causes the average kinetic energy of the copper atoms to increase, leading to more collisions and a higher resistance. Happy conducting at high temperatures!
