Question

The heat developed in a system is proportional to the current through it.

विकल्प

• It cannot be Thomson heat

• It cannot be Peltier heat

• It cannot be Joule heat

• It can be any of the three heats mentioned above

Answer 1

It cannot be Joule heat

 

Joule heat is directly proportional to the square of the current passing through the resistor. Peltier heat is directly proportional to the current passing through the junction.Thomson heat is also directly proportional to the current passing through the section of the wire. Thus, the heat developed can be either Thomson heat or Peltier heat. But it cannot be Joule heat.
