Question

A heat producing device should be used in an electric circuit this device should have A.high resistance and low melting point B.b low resistance and high melting point
C.high resistance and high melting point D.low resistance and low melting poin

Answer 1

Answer:

option B

Explanation:

It should have low resistance and high melting point so as to produce heat at a good level.

The low resistance will ensure that more of the circuit is heated and high melting point will protect it from melting.

Answer 2

Answer:

C. high resistance and high melting point

Explanation:

High resistance to produce heat,

high melting point so that the material does not break down due to this strong heat developed
