Question

In which of the following the power dissipation is proportional to the square of the current?(a) Peltier effect(b) Joule's effect(c) Thomson effect(d) None of the above

Answer 1

Among the four options mentioned in the question,the joule's effect is proportional to the square of the current.

Because,according the joules law a specific amount of heat is produced when the electricity passes through the conductor wire

And this amount of heat is directly proportional with the square of the current.

That's why the correct answer of this question is option b.
