Derive an expression for joule law of heating
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 ... 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 …
