explain the joule law of heating
Answers
Answer:
Joule heating, also known as resistance heating (resistive heating) and Ohmic heating, is the process by which the passage of an electric current through a conductor produces heat.
Joule's first law, also known as the Joule–Lenz law,[1] states that the power of heating generated by an electrical conductor is proportional to the product of its resistance and the square of the current:
Joule heating affects the whole electric conductor, unlike the Peltier effect which transfers heat from one electrical junction to another.
hope its help
plzzzzzz mark it as brainliest

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.
i hope it helps you.
