25.
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.
