If conductance increases as temperature increases, this is known as a:
positive coefficient
negative current flow
negative coefficient
positive resistance
Answer: Option
Explanation:

A negative temperature coefficient (NTC) occurs when the thermal conductivity of a material rises with increasing temperature, typically in a defined temperature range.

Note: The reciprocal of electrical Resistance is called Conductance.

No, when temperature increase conductance increase that is called positive temperature coefficient.

NTC(T)proportional to 1/R(resistance).
If temperature increase resistance decrease.

The reciprocal of resistance is called conductance,

G(conductance). =1/R.
NTC(T) proportional to conductance.

Then temperature increase conductance increase.

Temperature is inversely to conductance but here process is reverse.

When temperature increases, conductance also increases. Then it is positive coefficient na? if no Please explain!
