Detailed Solution
Download Solution PDFProperties of a Good Heating Element:
A good heating element should have the following properties:
- High resistivity: This ensures that the element can generate sufficient heat when current passes through it.
- High melting point: This allows the heating element to operate at high temperatures without melting.
- Low-temperature coefficient of resistance: This ensures that the resistance of the element does not change significantly with temperature, maintaining consistent heating performance.
- Low specific heat capacity: This ensures that the element heats up quickly and does not require a lot of energy to reach the desired temperature.
Based on the above properties High melting point & Low-temperature coefficient of resistance are correct options.
