WebJan 30, 2024 · The First Law of Thermodynamics states that energy can be converted from one form to another with the interaction of heat, work and internal energy, but it cannot be created nor destroyed, under any circumstances. Mathematically, this is represented as. (1) Δ U = q + w. with. Δ U is the total change in internal energy of a system, q is the ... WebApr 2, 2024 · E = P t. From (1) E = I 2 R t. Since the power is the power of heating, the energy obtained is the heat energy. So we get the mathematical expression for Joule’s …
Webκ A ∂ T ∂ x ( x, t) For the temperature gradients to be positive on both sides, temperature must increase. As the heat flows from the hot region to a cold region, heat energy should enter from the right end of the rod to the left end of the rod. Therefore, κ A ∂ T ∂ x ( x + d x, t) − κ A ∂ T ∂ x ( x, t) d t. Where, dt ... WebNov 1, 2024 · Applying the idea, we arrive at the equation. δ Q = δ W = − q d φ. After integration we have Q = q ⋅ ( − Δ φ) = q V. Knowing that q = I Δ t, we obtain the terminal expression Q = I V Δ t. That is the formula, given in the Wikipedia. The derivation is based upon my understanding. thermodynamics. Share. Cite.
WebMar 29, 2024 · Joule’s law of heating states that the heat produced in a conductor is directly proportional to (i) the square of the current I through it, (ii) its resistance R and (iii) the time t , for which current is passed. Therefor, the mathematical expression of Joule’s law of heating is: H = I 2 Rt Where, H = Produced Heat WebWrite the mathematical expression for Joule's law of heating. Medium Solution Verified by Toppr According to Joule's law, when a current is passed through a conductor for a certain time, the conductor gets heated up and the amount of heat (H) is given by : H=i 2Rt H is the heat, i is the current, R is the resistance, and t is the time.
