a) Heat produced is directly proportional to the square of the current passing by a conductor.
b) This effect is produced because of collision of free electrons with positive ions of the current carrying conductor.
c) It is not a reversible effect.
d) Heat produced depends upon resistance (and therefore temperature also) of the conductor.
e) It is mainly a heating effect
