25.

If conductance increases as temperature increases, this is known as a:

A.	positive coefficient
B.	negative current flow
C.	negative coefficient
D.	positive resistance

Answer: Option C

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.
