Correct Answer: copper decreases and germanium increases
Explanation:
As temperature is decreased, resistance of conductors decreases and resistance of semiconductors increases.
5. When a dielectric is subjected to an electric field E, each volume element of dielectric can be considered to be carrying an electric dipole moment.
9. In a specimen of silicon steel, a field strength of 200 A/m causes a flux density of 0.5 T. In a specimen of cast iron, the same H would cause B to be
