एक ऋणात्मक तापमान गुणांक (NTC) थर्मिस्टर और एक निश्चित प्रतिरोधक (fixed resistor) वाले श्रृंखला (series) सर्किट में, जो एक स्थिर DC बिजली आपूर्ति से जुड़े हैं, तापमान में वृद्धि का निश्चित प्रतिरोधक के पार मिलने वाले आउटपुट वोल्टेज पर क्या प्रभाव पड़ेगा?

Consider the following technological actions: 1. Detection of a car crash/collision which results in the instantaneous deployment of airbags. 2. Detection of accidental free fall of a laptop towards the ground which results in the immediate turning off of the hard drive. 3. Detection of the tilt of a smartphone which results in the rotation of the display between portrait and landscape modes. In how many of the above actions is the function of an accelerometer required?
