Thermoelectric Effect
Introduction The thermoelectric effect refers to a collection of phenomena in which a temperature difference creates an electric potential or an electric potential creates a temperature difference. These effects have important applications in heating and cooling, power generation, and temperature sensing. Types of Thermoelectric Effects Seebeck Effect The Seebeck effect is the conversion of temperature…

Joule’s Law
Introduction Joule’s Law, named after the English physicist James Prescott Joule, is a fundamental principle in the field of electrical engineering and physics. It describes the relationship between the heat generated and the current flowing through a conductor. Basic Formulation Joule’s Law can be expressed as: where: The heat is measured in joules (J), current…

Heat
Introduction Heat is a form of energy that is transferred between systems or objects with different temperatures, flowing from the higher temperature system to the lower temperature one until equilibrium is reached. Heat and Thermodynamics In the context of thermodynamics, heat is described as the energy transferred across the boundary of a system due to…
