Question

Mention two characteristics of heating element of heater?

Answer 1

1 . A Heating element wire should have high melting point and it has low thermal extension.
2 . a high value of specific resistance.
A Fuse wire should have high resistivity, low melting point and suitable current rating corresponding to the load in the circuit.

Answer 2

* A Heating element wire should have high melting point and it has low thermal extension. 
* There should be high value of specific resistance.
