1) The temperature dependence of resistance of Cu and undoped Si in the temperature range 300-400 K, is best described by A) Linear increase for Cu, linear increase for Si B) linear increase for Cu, exponential increase for Si C) linear increase for Cu, exponential decrease for Si D) Linear decrease for Cu, linear decrease for Si Answer: Option CExplanation:As we know CU is a conductor , so an increase in temperature, resistance will increases. Then, Si semiconductor, so with increases in temperature, resistance will decreases
