Q1 Sometimes it is said that "heat is developed in" in a resistance when there is electric current in it. Recall heat is defined as energy due to temperature difference. Is the statement under quotes technically correct?


Q2 When a current is estabished in a wire, the free electrons drift in the direction opposite to the current. Does the number of free electrons in a wore continuously decrease?

Dear Nikhil,


(a)


Technically the correct statement would be "Temperature of the resistance increases.". In language though the statement is ok as temperature increase sets stage for heat flow. 


(b) 


Number of free electrons doesn't decrease because what is lost from one end of wire is gained from another end.


Please feel free to post as many doubts on our discussion forum as you can.we will get you the answer and detailed  solution very  quickly. All the best.
