Correct Answer: 11.3 V
Correct Answer: carbon
Correct Answer: crystal
Correct Answer: depletion region
Correct Answer: hole
Correct Answer: negative coefficient
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.
Correct Answer: heat
Correct Answer: 0.7
Correct Answer: arsenic
Correct Answer: pentavalent material
