10. The following table gives the resistivity of: Three samples:Resistivity - 1.6×10^-8 -5.2×10^-8 - 100×10^-6 ohm mWhich of these is suitable for making heating elements of electrical appliances and why?​

Answer» <html><body><p>The standard resistors are made of materials for which the resistivity is <a href="https://interviewquestions.tuteehub.com/tag/quite-2238067" style="font-weight:bold;" target="_blank" title="Click to know more about QUITE">QUITE</a> <a href="https://interviewquestions.tuteehub.com/tag/large-1066424" style="font-weight:bold;" target="_blank" title="Click to know more about LARGE">LARGE</a> and effect of <a href="https://interviewquestions.tuteehub.com/tag/change-913808" style="font-weight:bold;" target="_blank" title="Click to know more about CHANGE">CHANGE</a> of temperature on their resistance is negligible. So C is suitable for heating elements of electrical appliances among the given as it has more resistivity 100 ⨯100⨯10 -<a href="https://interviewquestions.tuteehub.com/tag/8-336412" style="font-weight:bold;" target="_blank" title="Click to know more about 8">8</a> Ω m = 10,000 ⨯ 10 -8 Ω m</p><p></p></body></html>
