Question

The same amount of current is passing through two conductors P and Q. Conductor P caused more obstruction to the flow of current as compared to Q. Which among the two will get heat up more?

Answer 1

c

Explanation:

A conductor has its own resistance. Due to the flowing current, certain heat is produced in the conductor according to the Joule's heating effect i.e H=I

2

Rt.

Thus electrical energy is converted into heat energy when a current flows through the conductor.
