Question

what joule law of heating in short

Answer 1

joules law of hearing states that h=I2RT

.......
IT IS SIMPLEST......

see,h=I2 when R AND T ARE CONSTANT....

AND....H=R WHRN I2 AND T ARE CONSTANT AND

H=T WHEN R AND I2 ARE CONSTANT....

Answer 2

hi mate,

we know that the Joule Heating Definition

Joule heating (also referred to as resistive or ohmic heating) describes the process where the energy of an electric current is converted into heat as it flows through a resistance.

Joule's law of heating states that , "The heat produced in a resistor is directly proportional to (1) square of current (I^2) (2) resistance of the resistor (R) and (3) time for which the current flows through the resistor .

This law governs the heating effect of current as heat energy released by a conductor when current passes through it. If the conductor is having resistance R and current I passes through it for time t, the heat energy dissipated, Q = I^2 X R X t.

Joule heating, also known as resistive, resistance, or Ohmic heating, is the process by which the passage of an electric current through a conductor produces heat.

i hope it helps you..
