6.
With increase in temperature, the electrical conductivity would
Answer: Option
Explanation:
Increase in temperature causes resistivity of metals to increase and resistivity of intrinsic semiconductors to decrease.
Conductivity is reciprocal of resistivity.
7.
An electron for which l = 0 has zero orbital magnetic dipole moment.
8.
The resistance of a metallic wire would
Answer: Option
Explanation:
As increases the resistance increases due to skin effect.
9.
If a small amount of Cu is added to Ni conductor, then
10.
