Q. A strip of copper and another germanium are cooled from room temperature to $80\, K$. The resistance of

AIEEEAIEEE 2003Semiconductor Electronics: Materials Devices and Simple Circuits

Solution:

The temperature coefficient of resistance of copper is positive and that of germanium is negative, therefore when copper and germanium are cooled, resistance of copper strip decreases and that of germanium increases.
