The oxide which shows metallic conduction is

The oxide which shows transition from metal to insulation, i.e., semiconductors are:

Which of the following shows electrical conduction ?

Which of the following shows electrical conduction ?

Which non-metal conduct electricity ?

The effect of temperature increases, : electrolytic conduction decreases , Metallic conduction increases, metallic conduction decreases, Electrolytic conduction increases, metallic conduction decreases, Both electrolytic and metallic conduction decreases, Both electrolytic and metalllic conduction increases

Electrolytic conduction differs from metallic conduction. In case of metallic conduction -
