- प्रतिरोध का तापमान गुणांक तापमान में बदलाव द्वारा प्रतिरोध में भिन्नता का वर्णन करता है। इसे ओम/ओम °C में व्यक्त किया जाता है।
- यदि यह धनात्मक होता है, तो तापमान में वृद्धि के साथ प्रतिरोध बढ़ता है।
- यदि यह ऋणात्मक होता है, तो तापमान में वृद्धि के साथ प्रतिरोध कम होता है।
Among the given options, the electrolyte has a negative temperature coefficient.
All metals and alloys of metals show a positive temperature coefficient.
Important Notes:
Conductors have a positive temperature coefficient.
