A peice of copper and the other of germanium are cooled from the room

1.	A peice of copper and the other of germanium are cooled from the room temperature to `80K`, then which of the following would be a correct statement?A. Resistance of each increasesB. Resistance of each decreasesC. Resistance of copper increases whil that of germenium decreasesD. Resistance of copper decreases while that of germenium increases
Answer» Correct Answer - B Resistance of conductors `(Cu)` decreases with decreas in temperature while that of semi-conductors `(Ge)` increases with decreases in temperature.
