Which property of a wire is used in making the heating element of an electric kettle?
AHigh conductivity
BLow resistivity
CHigh resistivity and high melting point
DLow melting point
✓ Correct Answer: C — High resistivity and high melting point
Heating elements need high resistivity to generate heat (I^2R) and high melting points so they don't break under heat.
