In general, Joule heating can be described as the physical effect that increases the internal energy and collision of electrons in a circuit carrying current, resulting in the generation of heat energy. In the Joule heating process, depending on the circuit conditions, some portion of electrical e...
Joule heating is often an undesirable effect because the generated heat means lost energy. In electronic devices, the Joule phenomenon causes heat to escape inside the device and requires heat reduction to work correctly. That's why electronic devices such as computers need to be cooled. On the...
wondered about the amount of heat generated during the flow of current through a wire and the parameters and conditions it is based upon. to answer all these questions, joule gave a formula that describes this phenomenon precisely and called it joule’s law. joule’s law of heating joule’s...
Joule heating effect - qualitative explanation Hi, I understand mathematically why using low resistance results in a greater heating effect. Could someone give an intuitive and microscopic picture of why the current contributes more to a greater power dissipation by the resistor rather than the resis...
However, owing to the inevitable thermal effect (Joule heating), the athermal effect on microstructural modifications remains obscure. This paper presents an approach of utilizing pre-micromachined structures, which obstruct current flow but maintain a thermal history similar to that of the matrix, ...
