Question

2. A heat producing device should be used in an electric circuit. This device
should have
A)high resistance and low melting point
B) low resistance and high melting point
C) high resistance and high melting point
D) low resistance and low melting point​

Answer 1

The 'heat producing device' should have "high resistance and high melting point".

Answer - (Option C)

Explanation:

• Since we are given a device that is being talked about and heat is produced device that is placed in an electric circuit.
• So, this device has to produce heat so it should be 'able to resist' the heat which is produced by itself.
• Hence it should have a high resistance and high melting point so that it doesn't melt while production of high temperature.
