Joule heating, also known as ohmic heating and resistive heating, is the process by which the passage of an electric current through a conductor releases heat. The amount of heat released is proportional to the square of the current such that.
Q proportional I^2.
It doesn't depend on direction.

Here, H=I2RT.
H=heat energy.
I=current flowing through wire.
R=its resistance.
T=time.

Heat =power.
Power =IV.
V=IR.
Then Heat =I*IR,
= I^2R.
Power =IV.
V=IR.
Then Heat =I*IR,
= I^2R.
