What is joule's law of heating?
Explain it briefly.
Answers
Answer:
Joule's law states the amount of heatproduction in a conductor is : Directly proportional to the square of electric current flowing through it. Is directly proportional to the resistance of the conductor. Directly proportional to the time for which electric current flows through the conductor.
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.
Answer: 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.
