WebMar 16, 2024 · This is known as Joule's law of heating. The law implies that the heat produced in a resistor is directly proportional to the square of current for a given resistance It means if we double the current,the heat becomes 4 times if we half the current,the heat becomes 1/4 times Hence,more the current,more the heat. Less the current, less heat … WebIt can be represented mathematically as. Δ Q = Δ U + W. Where, ΔQ is the heat given or lost. ΔU is the change in internal energy. W is the work done. We can also represent the above equation as follows, Δ U = Δ Q − W. So we can infer from the above equation that the quantity (ΔQ – W) is independent of the path taken to change the state.

WebJan 23, 2024 · When the temperature of the resistor is greater than the temperature of its environment, there is heat transfer to its environment. A rough mechanical analogy is the mechanical work moving an object at constant velocity on a surface with friction. All the work in moving the object between two points is converted to heat due to kinetic friction. 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. Joule's first law (also just Joule's law), also known in countries of former USSR as the Joule–Lenz law, states that the power of heating generated by an electric…
