Dj low resistance and low melting point​

Answer 1

Answer:

d) heat producing device should have low resistance and low melting point

because to avoiding opposition of current and to avoid melting of device metal

I hope this will help you

Answer 2

A heat producing device should be used in an electric circuit. This device

should have low resistance and high melting point.  

Option b)

Explanation:

• Low resistance is required as this would enable the device to be used in the electric circuit or else if the resistance was too high then the electrons cannot flow through it effectively and they would lose their kinetic energy much.
• On the other hand, this is a heat-producing device and therefore this would get heated.
• If it has a low melting point the device can melt and it would stop functioning. Hence, a high melting point is required.
